Digital imaging systems and methods of analyzing pixel data of an image of a user's body after removing hair for determining a user-specific hair removal efficiency value

## Abstract

A digital imaging method of analyzing pixel data of an image of a user's body for determining a user-specific hair removal efficiency value after removing hair is disclosed. The digital imaging method includes: aggregating training images of respective individuals' bodies after removing hair; training, using the pixel data of the training images, a hair removal efficiency model to determine hair removal efficiency values associated with a degree of hair removal efficiencies ranging from a least efficient to a most efficient; receiving an image of a user's body after removing hair; analyzing by the user image using the hair removal efficiency model to determine a user-specific hair removal efficiency value; generating a user-specific electronic recommendation designed to address a feature identifiable within the pixel data of the user's body based on the user-specific hair removal efficiency value; and rendering the recommendation on a display screen of a user computing device.

## Background
FIELD
The present disclosure generally relates to digital imaging systems and methods, and more particularly to, digital imaging systems and methods for analyzing pixel data of an image of a user's body after removing hair for determining a user-specific hair removal efficiency value.
BACKGROUND
Generally, individuals today who wish to remove hair from various areas of their bodies have the option of using many different hair removal methods, including shaving using a wet razor, shaving using a dry shaver, epilators, light based hair removal devices, depilatory creams, waxes, and other methods. Variations in individuals' expertise levels with different hair removal methods, sensitivity levels, hair thickness or curl, skin types, as well as variations in areas of the body where each individual is removing hair, can lead to varying levels of efficiency (i.e., measured based on amount of hair remaining, length of remaining hair protruding above the surface level of the skin, etc.) for each of these hair removal methods between individuals. That is, one user may very efficiently remove hair using a wet razor, while another user using the same wet razor may find that an unsatisfactory amount of hair remains after use. Inefficient hair removal can be frustrating for users, and, additionally, can cause users to attempt additional hair removal (e.g., additional shave strokes, additional application of wax, use of a second method of hair removal, etc.) over a shorter timeframe, which may lead to skin irritation.
Thus, a problem arises for existing hair removal methods, and the use thereof, where individuals knowingly or unknowingly utilize hair removal methods that are inefficient for their specific needs. The problem is acutely pronounced given the various versions, brands, and types of hair removal methods currently available to individuals, where each of these different versions, brands, and types of hair removal methods have different ingredients, components, blades, sharpness, and/or otherwise different configurations, all of which can affect their efficiency for users having varying expertise levels in using the products, sensitivity levels, hair thickness or curl, skin types, etc., as well for varying areas of the body where each individual is removing hair. This problem is particularly acute because such existing hair removal methods provide little or no feedback or guidance to assist the individual in determining hair removal efficiency or comparing hair removal efficiency between methods.
For the foregoing reasons, there is a need for digital imaging systems and methods for analyzing pixel data of an image of a user's body after removing hair for determining a user-specific hair removal efficiency value.
SUMMARY
Generally, as described herein, the digital imaging systems and methods for analyzing pixel data of an image of a user's body after removing hair for determining a user-specific hair removal efficiency value provide a digital imaging and artificial intelligence (AI) based solution for overcoming problems that arise from inefficiency in hair removal methods. The digital systems and methods allow a user to submit a specific user image to imaging server(s) (e.g., including its one or more processors), or otherwise a computing device (e.g., such as locally on the user's mobile device), where the imaging server(s) or user computing device implements or executes a hair removal efficiency model trained with pixel data of potentially 10,000s (or more) images of individuals after removing hair. The hair removal efficiency model may generate, based on a determined user-specific hair removal efficiency value, a user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data comprising at least a portion of the user's body or body area after removing hair. For example, the at least one feature can comprise pixels or pixel data indicative of a measure of remaining hairs protruding above the surface level of the user's skin, i.e., a number of remaining hairs, a density of remaining hairs, or a length of remaining hairs after removing hair. In some embodiments, the user-specific recommendation (and/or product specific recommendation) may be transmitted via a computer network to a user computing device of the user for rendering on a display screen. In other embodiments, no transmission to the imaging server of the user's specific image occurs, where the user-specific recommendation (and/or product specific recommendation) may instead be generated by the hair removal efficiency model, executing and/or implemented locally on the user's mobile device and rendered, by a processor of the mobile device, on a display screen of the mobile device. In various embodiments, such rendering may include graphical representations, overlays, annotations, and the like for addressing the feature in the pixel data.
More specifically, as described herein, a digital imaging method of analyzing pixel data of at least one image of a user's body for determining a user-specific hair removal efficiency value after removing hair is disclosed. The digital imaging method comprises the steps of: aggregating, at one or more processors communicatively coupled to one or more memories, a plurality of training images of a plurality of individuals after removing hair, each of the training images comprising pixel data of a respective individual's body or body area after removing hair; training, by the one or more processors, with the pixel data of the plurality of training images, a hair removal efficiency model operable to determine hair removal efficiency values associated with a degree of hair removal efficiencies ranging from a least efficient to a most efficient; receiving, at the one or more processors at least one image of a user, the at least one image captured by a digital camera, and the at least one image comprising pixel data of the user's body or body area after removing hair; analyzing by the hair removal efficiency model executing on the one or more processors, the at least one image captured by the digital camera to determine a user-specific hair removal efficiency value; generating, by the one or more processors, based on the user-specific hair removal efficiency value, at least one user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data of the user's body or body area; and rendering, on a display screen of a user computing device, the at least one user-specific electronic recommendation.
In addition, as described herein, a digital imaging system is disclosed, configured to analyze pixel data of at least one image of a user's body for determining a user-specific hair removal efficiency value after removing hair. The digital imaging system may comprise an imaging server comprising a server processor and a server memory; an imaging application (app) configured to execute on a user computing device comprising a device processor and a device memory, the imaging app communicatively coupled to the imaging server; and a hair removal efficiency model trained with pixel data of a plurality of training images of individuals and operable to determine hair removal efficiency values associated with a degree of hair removal efficiencies ranging from a least efficient to a most efficient, wherein the hair removal efficiency model is configured to execute on the server processor or the device processor to cause the server processor or the device processor to: receive at least one image of a user, the at least one image captured by a digital camera, and the at least one image comprising pixel data of the user's body or body area after removing hair, analyze, by the hair removal efficiency model, the at least one image captured by the digital camera to determine a user-specific hair removal efficiency value, generate, based on the user-specific hair removal efficiency value, at least one user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data comprising the user's body or body area after removing hair, and render, on a display screen of the user computing device of the user, the at least one user-specific electronic recommendation.
Further, as described herein, a tangible, non-transitory computer-readable medium storing instructions for analyzing pixel data of at least one image of a user's body for determining a user-specific hair removal efficiency value after removing hair is disclosed. The instructions, when executed by one or more processors, may cause the one or more processors to: aggregate, at one or more processors communicatively coupled to one or more memories, a plurality of training images of a plurality of individuals, each of the training images comprising pixel data of a respective individual after removing hair; train, by the one or more processors with the pixel data of the plurality of training images, a hair removal efficiency model operable to determine hair removal efficiency values associated with a degree of hair removal efficiencies ranging from a least efficient to a most efficient; receive, at the one or more processors, at least one image of a user, the at least one image captured by a digital camera, and the at least one image comprising pixel data of the user's body or body area after removing hair; analyze, by the hair removal efficiency model executing on the one or more processors, the at least one image captured by the digital camera to determine a user-specific hair removal efficiency value; generate, by the one or more processors based on the user-specific hair removal efficiency value, at least one user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data comprising the user's body or body area after removing hair; and render, on a display screen of a user computing device, the at least one user-specific electronic recommendation.
In accordance with the above, and with the disclosure herein, the present disclosure includes improvements in computer functionality or in improvements to other technologies at least because the disclosure describes that, e.g., an imaging server, or otherwise computing device (e.g., a user computer device), is improved where the intelligence or predictive ability of the imaging server or computing device is enhanced by a trained (e.g., machine learning trained) hair removal efficiency model. The hair removal efficiency model, executing on the imaging server or computing device, is able to accurately identify, based on pixel data of other individuals, a user-specific hair removal efficiency value and a user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data of a specific user's body or body area after removing hair. That is, the present disclosure describes improvements in the functioning of the computer itself or “any other technology or technical field” because an imaging server or user computing device, is enhanced with a plurality of training images (e.g., 10,000 s of training images and related pixel data as feature data) to accurately predict, detect, or determine pixel data of a user-specific images, such as newly provided customer images. This improves over the prior art at least because existing systems lack such predictive or classification functionality and are simply not capable of accurately analyzing user-specific images to output a predictive result to address at least one feature identifiable within the pixel data comprising the at least one image of the user's body or body area after removing hair.
For similar reasons, the present disclosure relates to improvement to other technologies or technical fields at least because the present disclosure describes or introduces improvements to computing devices in the field of hair removal, whereby the trained hair removal efficiency model executing on the imaging devices or computing devices improve the field of hair removal with digital and/or artificial intelligence based analysis of user or individual images to output a predictive result to address at least one feature identifiable within the user-specific pixel data of the user's body or body area after removing hair.
In addition, the present disclosure includes specific features other than what is well-understood, routine, conventional activity in the field, or adding unconventional steps that confine the claim to a particular useful application, e.g., analyzing pixel data of an image of a user's body after removing hair for determining a hair removal efficiency value, as described herein.

As will be realized, the present embodiments may be capable of other and different embodiments, and their details are capable of modification in various respects.

For example, a digital camera and/or digital video camera of, e.g., any of user computing devices 111c1-111c3 and/or 112c1-112c3 may be configured to take, capture, or otherwise generate digital images (e.g., pixel based images 202a, 202b, and/or 202c) and, at least in some embodiments, may store such images in a memory of a respective user computing devices.
Still further, each of the one or more user computer devices 111c1-111c3 and/or 112c1-112c3 may include a display screen for displaying graphics, images, text, product recommendations, data, pixels, features, and/or other such visualizations or information as described herein. In various embodiments, graphics, images, text, product recommendations, data, pixels, features, and/or other such visualizations or information may be received by imaging server(s) 102 for display on the display screen of any one or more of user computer devices 111c1-111c3 and/or 112c1-112c3. Additionally, or alternatively, a user computer device may comprise, implement, have access to, render, or otherwise expose, at least in part, an interface or a guided user interface (GUI) for displaying text and/or images on its display screen.
FIGS. 2A-2C illustrate example images 202a, 202b, and 202c that may be collected or aggregated at imaging server(s) 102 and may be analyzed by, and/or used to train, a hair removal efficiency model (e.g., an AI model such as a machine learning imaging model as described herein). Each of these images may comprise pixel data (e.g., RGB data) representing feature data and corresponding to each of the personal attributes of the respective users 202au, 202bu, and 202cu, within the respective image. The pixel data may be captured by a digital camera of one of the user computing devices (e.g., one or more user computer devices 111c1-111c3 and/or 112c1-112c3).
Generally, as described herein, pixel data (e.g., pixel data 202ap, 202bp, and/or 202cp) comprises individual points or squares of data within an image, where each point or square represents a single pixel (e.g., pixel 202ap1 and pixel 202ap2) within an image. Each pixel may be a specific location within an image. In addition, each pixel may have a specific color (or lack thereof). Pixel color may be determined by a color format and related channel data associated with a given pixel. For example, a popular color format includes the red-green-blue (RGB) format having red, green, and blue channels. That is, in the RGB format, data of a pixel is represented by three numerical RGB components (Red, Green, Blue), that may be referred to as channel data, to manipulate the color of pixel's area within the image. In some implementations, the three RGB components may be represented as three 8-bit numbers for each pixel. Three 8-bit bytes (one byte for each of RGB) is used to generate 24 bit color. Each 8-bit RGB component can have 256 possible values, ranging from 0 to 255 (i.e., in the base 2 binary system, an 8 bit byte can contain one of 256 numeric values ranging from 0 to 255). This channel data (R, G, and B) can be assigned a value from 0 255 and be used to set the pixel's color. For example, three values like (250, 165, 0), meaning (Red=250, Green=165, Blue=0), can denote one Orange pixel. As a further example, (Red=255, Green=255, Blue=0) means Red and Green, each fully saturated (255 is as bright as 8 bits can be), with no Blue (zero), with the resulting color being Yellow. As a still further example, the color black has an RGB value of (Red=0, Green=0, Blue=0) and white has an RGB value of (Red=255, Green=255, Blue=255). Gray has the property of having equal or similar RGB values. So (Red=220, Green=220, Blue=220) is a light gray (near white), and (Red=40, Green=40, Blue=40) is a dark gray (near black).
In this way, the composite of three RGB values creates the final color for a given pixel. With a 24-bit RGB color image using 3 bytes there can be 256 shades of red, and 256 shades of green, and 256 shades of blue. This provides 256×256×256, i.e., 16.7 million possible combinations or colors for 24 bit RGB color images. In this way, the pixel's RGB data value shows how much of each of Red, and Green, and Blue comprise the pixel. The three colors and intensity levels are combined at that image pixel, i.e., at that pixel location on a display screen, to illuminate a display screen at that location with that color. In is to be understood, however, that other bit sizes, having fewer or more bits, e.g., 10-bits, may be used to result in fewer or more overall colors and ranges.
As a whole, the various pixels, positioned together in a grid pattern, form a digital image (e.g., pixel data 202ap, 202bp, and/or 202cp). A single digital image can comprise thousands or millions of pixels. Images can be captured, generated, stored, and/or transmitted in a number of formats, such as JPEG, TIFF, PNG and GIF. These formats use pixels to store represent the image.
FIG. 2A illustrates an example image 202a and its related pixel data (e.g., pixel data 202ap) that may be used for training and/or implementing a hair removal efficiency model (e.g., hair removal efficiency model 108), in accordance with various embodiments disclosed herein.

FIG. 3 illustrates a diagram of a digital imaging method 300 of analyzing pixel data of an image (e.g., images 202a, 202b, and/or 202c) of a user's body after removing hair for determining a hair removal efficiency value, in accordance with various embodiments disclosed herein. Images, as described herein, are generally pixel images as captured by a digital camera (e.g., a digital camera of user computing device 111c1). In some embodiments an image may comprise or refer to a plurality of images such as a plurality of images (e.g., frames) as collected using a digital video camera. Frames comprise consecutive images defining motion, and can comprise a movie, a video, or the like.
At block 302, the method 300 comprises aggregating, at one or more processors communicatively coupled to one or more memories, a plurality of training images of a plurality of individuals after removing hair, each of the training images comprising pixel data of a respective individual's body or body area after removing hair (e.g., using a wet razor, a dry shaver, an epilator, a light based hair removal device, a depilatory cream, a wax, etc.). For instance, in some examples, the one or more processors include at least one of a server or a cloud-based computing platform, and the server or the cloud-based computing platform receives the plurality of training images of the plurality of individuals via a computer network.
At block 304, the method 300 comprises training, by the one or more processors with the pixel data of the plurality of training images, a hair removal efficiency model (e.g., hair removal efficiency model 108) operable to determine hair removal efficiency values associated with a degree of hair removal efficiencies ranging from a least efficient to a most efficient. In various embodiments, the hair removal efficiency model is an artificial intelligence (AI) based model trained with at least one AI algorithm.
In some examples, the hair removal value may be a scaled value. The hair removal efficiency scale can be an internalized scale or otherwise custom scale, unique to the hair removal efficiency model, where a least or small hair removal efficiency value may be determined from an image or set of images having skin areas with low hair removal efficiency values, i.e., images where the pixel data indicates higher values for the amount of hair, density of hair, or length of hair after hair removal. Similarly, a most or large hair removal efficiency value may be determined from an image or set of images having body areas with high hair removal efficiency values, i.e., images where the pixel data indicates that the user's body or body area has a lower amount of hair or lower density of hair, or a shorter length of hair after hair removal.
In some embodiments, the hair removal efficiency scale may be a percentage scale, e.g., outputting hair removal efficiency values from 0% to 100%, where 0% represents least hair removal efficiency and 100% represents most hair removal efficiency. Values can range across this scale where a hair removal efficiency value of 67% represents one or more pixels of a skin area detected within an image that has a higher hair removal efficiency value than a hair removal efficiency value of 10% as detected for one or more pixels of a body or body area within the same image or a different image (of the same or different user).
In some embodiments, the hair removal efficiency scale may be a numerical or decimal based scale, e.g., outputting hair removal efficiency values, e.g., from 0 to 10, where 0 represents lowest hair removal efficiency and 10 represents greatest hair removal efficiency. Values can range across this scale where a hair removal efficiency value of 7 represents one or more pixels of a skin area detected within an image that has a higher hair removal efficiency value than a hair removal efficiency value of 2 as detected for one or more pixels of a body or body area within the same image or a different image (of the same or different user).
Hair removal efficiency values may be determined at the pixel level or for a given body area (e.g., one or more pixels) in an image.
In some embodiments, a comprehensive hair removal efficiency value, which can be a user-specific hair removal efficiency value as described herein, may be determined by averaging (or otherwise statistically analyzing) hair removal efficiency values for one or more pixels of a given body area.
In some examples, the server or the cloud-based computing platform discussed above with respect to block 302 trains the hair removal efficiency model with the pixel data of the plurality of training images.
Training of the hair removal efficiency model 108 involves image analysis of the training images to configure weights of hair removal efficiency model, and its underlying algorithm (e.g., machine learning or artificial intelligence algorithm) used to predict and/or classify future images. For example, in various embodiments herein, generation of hair removal efficiency model 108 involves training hair removal efficiency model 108 with the plurality of training images of a plurality of individuals, where each of the training images comprise pixel data of the user's body or body area after removing hair. In some embodiments, one or more processors of a server or a cloud-based computing platform (e.g., imaging server(s) 102) may receive the plurality of training images of the plurality of individuals via a computer network (e.g., computer network 120). In such embodiments, the server and/or the cloud-based computing platform may train the hair removal efficiency model 108 with the pixel data of the plurality of training images.
For example, in various embodiments, a machine learning imaging model as described herein (e.g. hair removal efficiency model 108), may be trained using a supervised or unsupervised machine learning program or algorithm. The machine learning program or algorithm may employ a neural network, which may be a convolutional neural network, a deep learning neural network, or a combined learning module or program that learns in two or more features or feature datasets (e.g., pixel data) in a particular areas of interest. The machine learning programs or algorithms may also include natural language processing, semantic analysis, automatic reasoning, regression analysis, support vector machine (SVM) analysis, decision tree analysis, random forest analysis, K-Nearest neighbor analysis, naïve Bayes analysis, clustering, reinforcement learning, and/or other machine learning algorithms and/or techniques. In some embodiments, the artificial intelligence and/or machine learning based algorithms may be included as a library or package executed on server(s) 102. For example, libraries may include the TENSORFLOW based library, the PYTORCH library, and/or the SCIKIT-LEARN Python library.
Machine learning may involve identifying and recognizing patterns in existing data (such as training a model based on pixel data within images having pixel data of respective individuals' bodies after removing hair) in order to facilitate making predictions or identification for subsequent data (such as using the model on new pixel data of a new individual's body after removing hair in order to determine a user-specific hair removal efficiency value).
Machine learning model(s), such as the hair removal efficiency model described herein for some embodiments, may be created and trained based upon example data (e.g., “training data” and related pixel data) inputs or data (which may be termed “features” and “labels”) in order to make valid and reliable predictions for new inputs, such as testing level or production level data or inputs. In supervised machine learning, a machine learning program operating on a server, computing device, or otherwise processor(s), may be provided with example inputs (e.g., “features”) and their associated, or observed, outputs (e.g., “labels”) in order for the machine learning program or algorithm to determine or discover rules, relationships, patterns, or otherwise machine learning “models” that map such inputs (e.g., “features”) to the outputs (e.g., labels), for example, by determining and/or assigning weights or other metrics to the model across its various feature categories. Such rules, relationships, or otherwise models may then be provided subsequent inputs in order for the model, executing on the server, computing device, or otherwise processor(s), to predict, based on the discovered rules, relationships, or model, an expected output.
In unsupervised machine learning, the server, computing device, or otherwise processor(s), may be required to find its own structure in unlabeled example inputs, where, for example multiple training iterations are executed by the server, computing device, or otherwise processor(s) to train multiple generations of models until a satisfactory model, e.g., a model that provides sufficient prediction accuracy when given test level or production level data or inputs, is generated. The disclosures herein may use one or both of such supervised or unsupervised machine learning techniques.
Image analysis may include training a machine learning based model (e.g., the hair removal efficiency model 108) on pixel data of images of one or more individuals' bodies after removing hair. Additionally, or alternatively, image analysis may include using a machine learning imaging model, as previously trained, to determine, based on the pixel data (e.g., including their RGB values) of one or more images of the body of the individual(s) after removing hair, a user-specific hair removal efficiency value after removing hair. The weights of the model may be trained via analysis of various RGB values of individual pixels of a given image. For example, dark or low RGB values (e.g., a pixel with values R=25, G=28, B=31) may indicate areas of the user's body having hair, as well as the density or length of the hair. Lighter RGB values (e.g., a pixel with R=181, G=170, and B=191) may indicate a lighter value, such as a skin tone color. When a large number of pixels having dark or low RGB values are positioned within a given image of an area of the user's body after removing hair, this may indicate that the user is not efficiently removing hair in the area of the user's body shown in the image. In this way, pixel data (e.g., detailing one or more features of an individual, such as the user's body or body area after removing hair) of 10,000s of training images may be used to train or use a machine learning imaging model to determine a user-specific hair removal efficiency value after removing hair.
In various embodiments, a hair removal efficiency model (e.g., hair removal efficiency model 108) may be further trained, by one or more processors (e.g., imaging server(s) 102), with the pixel data of the plurality of training images, to output one or more location identifiers indicating one or more corresponding body area locations of respective individuals. In such embodiments, the hair removal efficiency model (e.g., hair removal efficiency model 108), executing on the one or more processors (e.g., imaging server(s) 102) and analyzing the at least one image of the user, can determine a location identifier indicating a body area location of the user's body or body area. For example, body area locations may comprise a user's cheek, a user's neck, a user's head, a user's groin, a user's underarm, a user's chest, a user's back, a user's leg, a user's arm, or a user's bikini area. For example, each of images image 202a, 202b, and 202 illustrate example body area locations including a user's check, a user's underarm or armpit, and a user's leg, respectively.
With reference to FIG. 3, at block 306, the method 300 comprises receiving, at the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111c1), at least one image of a user. The at least one image may have been captured by a digital camera. In addition, the at least one image may comprise pixel data of the user's body or body area after removing hair (e.g., using a wet razor, a dry shaver, an epilator, a light based hair removal device, a depilatory cream, a wax, etc.). In some examples, the digital camera is a digital video camera, and the at least one image is a plurality of images. In some examples, the server or a cloud-based computing platform discussed above with respect to block 302 receives the at least one image. Moreover, in some examples, a user computing device (e.g., a mobile device, a tablet, a handheld device, a desktop device, etc.) receives the at least one image.
At block 308, the method 300 comprises analyzing, by the hair removal efficiency model (e.g., hair removal efficiency model 108) executing on the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111c1), the at least one image captured by the digital camera to determine a user-specific hair removal efficiency value (e.g., based on a number of missed hairs and/or a length of the missed hairs). In some examples, the server or a cloud-based computing platform discussed above with respect to block 302 analyzes the at least one image to determine the user-specific hair removal efficiency value. Furthermore, in some examples, the user computing device discussed above with respect to block 306 analyzes the at least one image to determine the user-specific hair removal efficiency value. Additionally, in some examples, the hair removal efficiency model 108 may further analyze the at least one image captured by the digital camera to determine a location identifier indicating a body area location of the user's body or body area (e.g., one of the user's face, the user's cheek, the user's neck, the user's jaw, the user's head, the user's groin, the user's underarm, the user's chest, the user's back, the user's leg, the user's arm, the user's bikini area, etc.).
At block 310, the method 300 comprises generating, by the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111c1), based on the user-specific hair removal efficiency value, at least one user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data of the user's body or body area. Moreover, in some examples, the server or a cloud-based computing platform discussed above with respect to block 302 generates the at least one user-specific recommendation and transmits the user-specific recommendation to the user computing device for rendering on the display screen of the user computing device. Furthermore, in some examples, the user computing device discussed above with respect to block 306 generates the at least one user-specific recommendation.
For instance, the user-specific recommendation may include at least one product recommendation for a manufactured product designed to address at least one feature identifiable within the pixel data of the user's body or body area. As another example, the user-specific recommendation may include a recommended shaving behavior, e.g., selected from two or more available behaviors based on the hair removal efficiency level.
At block 312, the method 300 comprises rendering, on a display screen of the user computing device, the at least one user-specific recommendation. A user computing device may comprise at least one of a mobile device, a tablet, a handheld device, or a desktop device, for example, as described herein for FIG. 1. In some embodiments, the user computing device (e.g., user computing device 111c1) may receive the at least one image comprising the pixel data of the user's body or body area. In such embodiments, the user computing device may execute the hair removal efficiency model (e.g., hair removal efficiency model 108) locally and generate, based on output of the hair removal efficiency model (e.g., hair removal efficiency model 108), the user-specific recommendation. The user computing device 111c1 may then render the user-specific recommendation on its display screen.
Additionally, or alternatively, in other embodiments, the imaging server(s) 102 may analyze the user image remotely from the user computing device to determine the user-specific hair removal efficiency value and/or user-specific electronic recommendation designed to address at least one feature identifiable within the pixel data comprising the user's body or body area. For example, in such embodiments imaging server or a cloud-based computing platform (e.g., imaging server(s) 102) receives, across computer network 120, the at least one image comprising the pixel data of at the user's body or body area. The server or a cloud-based computing platform may then execute the hair removal efficiency model (e.g., hair removal efficiency model 108) and generate, based on output of the hair removal efficiency model (e.g., hair removal efficiency model 108), the user-specific recommendation. The server or a cloud-based computing platform may then transmit, via the computer network (e.g., computer network 120), the user-specific recommendation to the user computing device for rendering on the display screen of the user computing device.
In some embodiments, the user may submit a new image to the hair removal efficiency model for analysis as described herein. In such embodiments, one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111c1) may receive a new image of the user after removing hair. The new image may been captured by a digital camera of user computing device 111c1. The new image may comprise pixel data of at least a portion of the user's body or body area. The hair removal efficiency model (e.g., hair removal efficiency model 108) may then analyze, on the one or more processors (e.g., imaging server(s) 102 and/or a user computing device, such as user computing device 111c1), the new image captured by the digital camera to determine a new user-specific hair removal efficiency value after removing hair. In some examples, the one or more processors may generate a delta hair removal efficiency value based on a comparison between the new user-specific hair removal efficiency value and the (initial or previous) hair removal efficiency value. A new user-specific electronic recommendation or comment may be generated, based on the new user-specific hair removal efficiency value or based on the delta hair removal efficiency value, regarding at least one feature identifiable within the pixel data of the new image. The new user-specific recommendation or comment (e.g., message) may then be rendered on a display screen of a user computing device of the user.
In some embodiments, a user-specific electronic recommendation may be displayed on the display screen of a user computing device (e.g., user computing device 111c1) with a graphical representation of the user's body or body area as annotated with one or more graphics or textual renderings corresponding to the user-specific hair removal efficiency value. In still further embodiments, the at least one user-specific electronic recommendation may be rendered in real-time or near-real time during or after the hair is removed.
In additional embodiments, a user-specific electronic recommendation may comprise a product recommendation for a manufactured product. In such embodiments, the user-specific electronic recommendation may be displayed on the display screen of a user computing device (e.g., user computing device 111c1) with instructions (e.g., a message) for treating, with the manufactured product, the at least one feature identifiable the pixel data comprising the at least the portion of the user's body or body area. In still further embodiments, either the user computing device 111c1 and/or imaging server(s) may initiate, based on the product recommendation, the manufactured product for shipment to the user.
FIG. 4 illustrates an example user interface 402 as rendered on a display screen 400 of a user computing device 111c1 in accordance with various embodiments disclosed herein. For example, as shown in the example of FIG. 4, user interface 402 may be implemented or rendered via an application (app) executing on user computing device 111c1.
For example, as shown in the example of FIG. 4, user interface 402 may be implemented or rendered via a native app executing on user computing device 111c1. In the example of FIG. 4, user computing device 111c1 is a user computer device as described for FIG. 1, e.g., where 111c1 is illustrated as an APPLE iPhone that implements the APPLE iOS operating system and has display screen 400. User computing device 111c1 may execute one or more native applications (apps) on its operating system. Such native apps may be implemented or coded (e.g., as computing instructions) in a computing language (e.g., SWIFT) executable by the user computing device operating system (e.g., APPLE iOS) by the processor of user computing device 111c1.
Additionally, or alternatively, user interface 402 may be implemented or rendered via a web interface, such as via a web browser application, e.g., Safari and/or Google Chrome app(s), or other such web browser or the like.
As shown in the example of FIG. 4, user interface 402 comprises a graphical representation (e.g., image 202a) of the user's skin. Image 202a may be the at least one image the user's body or body area (or graphical representation thereof) after removing hair and as analyzed by the hair removal efficiency model (e.g., hair removal efficiency model 108) as described herein. In the example of FIG. 4, graphical representation (e.g., image 202a) of the user's skin is annotated with one or more graphics (e.g., area of pixel data 202ap) or textual rendering (e.g., text 202at) corresponding to the efficiency of the user's hair removal or the extent to which the user's hair has been removed. For example, the area of pixel data 202ap may be annotated or overlaid on top of the image of the user (e.g., image 202a) to highlight the area or feature(s) identified within the pixel data (e.g., feature data and/or raw pixel data) by the hair removal efficiency model (e.g., hair removal efficiency model 108). In the example of FIG. 4, the area of pixel data 202ap and the feature(s) identified within the pixel data 202ap include the number of hairs remaining after hair removal, the density of remaining hair after hair removal, the length of remaining hair after hair removal, and other features shown in area of pixel data 202ap. In various embodiments, the pixels identified as the specific features indicating remaining hair (e.g., pixel 202ap1 as a dark pixel indicating where hair remains) may be highlighted or otherwise annotated when rendered.
Textual rendering (e.g., text 202at) shows a user-specific hair removal efficiency value (e.g., 4/10) which illustrates that the user's hair removal efficiency is below average for typical users (e.g., with 10 corresponding to a maximum hair removal efficiency value, 1 corresponding to a minimum hair removal efficiency value, and 5 corresponding to an average hair removal efficiency value). In particular, 4/10 value indicates that the user's hair removal is not very efficient compared to other users. It is to be understood that other textual rendering types or values are contemplated herein, where textual rendering types or values may be rendered, for example, as a range of 1 to 100, as a letter grade, or some other indication of a hair removal efficiency value. Additionally, or alternatively, color values may use and/or overlaid on a graphical representation shown on user interface 402 (e.g., image 202a) to indicate remaining hair after hair removal.
User interface 402 may also include or render a user-specific electronic recommendation 412. In the embodiment of FIG. 4, user-specific electronic recommendation 412 comprises a message 412m to the user designed to address at least one feature identifiable within the pixel data comprising the portion of the user's skin where hair has been removed. As shown in the example of FIG. 4, message 412m recommends to the user to switch to a razor having additional blades to increase his or her hair removal efficiency value. The product recommendation can be correlated to the identified feature within the pixel data, and the user computing device 111c1 and/or server(s) 102 can be instructed to output the product recommendation when the feature (e.g., large amount of remaining hair, high density of remaining hair, long length of remaining hair, etc.) is identified.
User interface 402 also include or render a section for a product recommendation 422 for a manufactured product 424r (e.g., a particular razor, a particular set of blades, a particular wax, a particular epilator, and/or a particular shaving gel or shaving cream). The product recommendation 422 generally corresponds to the user-specific electronic recommendation 412, as described above. For example, in the example of FIG. 4, the user-specific electronic recommendation 412 is displayed on display screen 400 of user computing device 111c1 with instructions (e.g., message 412m) for treating, with the manufactured product (manufactured product 424r (e.g., the particular razor, the particular set of blades, the particular wax, the particular epilator, and/or the particular shaving gel or shaving cream) at least one feature (e.g., the amount of hair remaining after removing hair, the density of remaining hair after removing hair, the length of hair after removing hair, etc., as shown at pixel 202ap 1) identifiable from the pixel data (e.g., pixel data 202ap) comprising the body or body area of the user after removing hair.
As shown in FIG. 4, user interface 402 recommends a product (e.g., manufactured product 424r (e.g., the particular razor, the particular wax, the particular epilator, and/or the particular shaving gel or shaving cream) based on the user-specific electronic recommendation 412. In the example of FIG. 4, the output or analysis of image(s) (e.g. image 202a) of the hair removal efficiency model 108, e.g., user-specific electronic recommendation 412 and/or its related values (e.g., hair removal efficiency value of 4/10) or related pixel data (e.g., 202ap1 and/or 202ap2) may be used to generate or identify recommendations for corresponding product(s). Such recommendations may include products such as the particular razor, the particular set of blades, the particular wax, the particular epilator, and/or the particular shaving gel or shaving cream, or the like to address the user-specific issue as detected within the pixel data by the hair removal efficiency model (e.g., hair removal efficiency model 108).
In the example of FIG. 4, user interface 402 renders or provides a recommended product (e.g., manufactured product 424r) as determined by the hair removal efficiency model (e.g., hair removal efficiency model 108) and its related image analysis of image 202a and its pixel data and various features. In the example of FIG. 4, this indicated and annotated (424p) on user interface 402.
User interface 402 may further include a selectable UI button 424s to allow a user (e.g., the user of image 202a) to select for purchase or shipment the corresponding product (e.g., manufactured product 424r). In some embodiments, selection of selectable UI button 424s a may cause the recommended product(s) to be shipped to the user (e.g., individual 501) and/or may notify a third party that the individual is interested in the product(s). For example, either user computing device 111c1 and/or imaging server(s) 102 may initiate, based on user-specific electronic recommendation 412, the manufactured product 424r (e.g., the particular razor, the particular set of blades, the particular wax, the particular epilator, and/or the particular shaving gel or shaving cream) for shipment to the user. In such embodiments, the product may be packaged and shipped to the user.
In various embodiments, graphical representation (e.g., image 202a), with graphical annotations (e.g., area of pixel data 202ap), textual annotations (e.g., text 202at), and/or user-specific electronic recommendations 412 may be transmitted, via the computer network (e.g., from an imaging server 102 and/or one or more processors) to user computing device 111c1, for rendering on display screen 400. In other embodiments, no transmission to the imaging server of the user's specific image occurs, where the user-specific recommendation (and/or product specific recommendation) may instead be generated locally, by the hair removal efficiency model (e.g., hair removal efficiency model 108) executing and/or implemented on the user's mobile device (e.g., user computing device 111c1) and rendered, by a processor of the mobile device, on display screen 400 of the mobile device (e.g., user computing device 111c1).
In some embodiments, any one or more of graphical representations (e.g., image 202a), with graphical annotations (e.g., area of pixel data 202ap), textual annotations (e.g., text 202at), user-specific electronic recommendation 412, and/or product recommendation 422 may be rendered (e.g., rendered locally on display screen 400) in real-time or near-real time during or after the hair removal. In embodiments where the image is analyzed by imaging server(s) 102, the image may be transmitted and analyzed in real-time or near real-time by imaging server(s) 102.
In some embodiments the user may provide a new image that may be transmitted to imaging server(s) 102 for updating, retraining, or reanalyzing by hair removal efficiency model 108. In other embodiments, a new image that may be locally received on computing device 111c1 and analyzed, by hair removal efficiency model 108, on the computing device 111c1.
In addition, as shown in the example of FIG. 4, the user may select selectable button 412i for reanalyzing (e.g., either locally at computing device 111c1 or remotely at imaging server(s) 102) a new image. Selectable button 412i may cause user interface 402 to prompt the user to attach a new image for analyzing. Imaging server(s) 102 and/or a user computing device such as user computing 111c1, may receive a new image of the user after removing hair. The new image may be captured by the digital camera. The new image (e.g., just like image 202a) may comprise pixel data of the body or body area of the user after removing hair. The hair removal efficiency model (e.g., hair removal efficiency model 108), executing on the memory of the computing device (e.g., imaging server(s) 102), may analyze the new image captured by the digital camera to determine a new user-specific hair removal efficiency value after the user removes hair again, or removes hair from a different body area. The computing device (e.g., imaging server(s) 102) may generate, based on the new hair removal efficiency value, a new user-specific electronic recommendation or comment regarding at least one feature identifiable within the pixel data of the new image. For example, the new user-specific electronic recommendation may include a new graphical representation including graphics and/or text (e.g., showing a new user-specific hair removal efficiency value, e.g., 8/10). The new user-specific electronic recommendation may include additional recommendations or additional information for the user, e.g., that the user has improved his or her hair removal efficiency as detected with the pixel data of the new image. In various embodiments, the new user-specific recommendation or comment may be transmitted via the computer network to the user computing device of the user for rendering on the display screen of the user computing device. In other embodiments, no transmission to the imaging server of the user's new image occurs, where the new user-specific recommendation (and/or product specific recommendation) may instead be generated locally, by the hair removal efficiency model (e.g., hair removal efficiency model 108) executing and/or implemented on the user's mobile device (e.g., user computing device 111c1) and rendered, by a processor of the mobile device, on a display screen of the mobile device (e.g., user computing device 111c1).
