FIG. 2 depicts abstraction model layers according to an embodiment of the present invention.
FIG. 3 is a block diagram of an example computer system including persistent storage which may be implemented according to an embodiment.

DETAILED DESCRIPTION
Current approaches for presenting and recommending filters for digital photographs to users include presenting static presets which are always available to the user via the software user interface of the device that is taking the photograph. Additional approaches include “auto mode”, in which the software analyzes the subject and scene to make adjustments based on, for example, either Bilateral Filtering or Histogram Enhancement. However, while these approaches are based on the latest algorithms available, the settings provided are often a fixed set that do not express an awareness of certain specific real-time conditions and therefore may not appeal to all users. Another example of a feature within the device capturing the image is high-dynamic-range (HDR) imaging, which takes multiple shots of the same scene and merges them to create a single image which averages the tones. This can be helpful but is a post-processing technique that depends on a fixed configuration to function.
To eliminate dependence on preconfigured software presets which do not take into account human interactions with photographs, an image classification model for predicting a human interaction score (“photo-resonance” model) is disclosed. According to various embodiments, the “photo-resonance” model may be derived from analysis of existing online images and their tagged human emotions or crowd sentiments, e.g., “liked” or ‘favorites’ from social media pages. The generalization of the model could further be used to reposition the filters within the user experience (UX) with the most popular filters at the top or to reconfigure the filters to use preemptive attributes for showing the most popular settings.
By using the “photo-resonance” model according to embodiments, dynamic auto enhancements may be derived and used for reranking photograph filters and associated settings on a camera to recommend only the settings that are popular in the UX. Incorporation into the model of GPS location and analysis of the most popular photographs around the location may provide faster and more accurate creation of auto-enhance presets dynamically. With the incorporation of crowd sentiment analysis, changes in trends of the most popular types or categories of filters at a geographical location can be determined in real-time. The model may use machine learning to improve itself through auto-adjustment and continuously transform the user experience.
In an embodiment, based on the GPS location of the device capturing the image and subject of the photograph, the “photo-resonance” model may analyze other images of the same location and subject to dynamically create a “best” auto-enhance preset to be used in real-time. For example, the most popular images for the cherry blossoms in Washington, D.C. may be analyzed to arrive at a recommended auto-enhance preset which reduces highlights to prevent overexposure of images since the cherry blossoms subject would usually be lighter in color than other elements in the photograph. As another example, in Antelope Canyon, Ariz., the typical main subject of photographs would be red sandstones, meaning that the most popular photographs may have a “warm” feel and the “photo-resonance” model may recommend a setting which enhances the color of the subject sandstones by reducing the intensity of blue pixels. Therefore, it is likely that most of the popular images analyzed by the model would have a lower count of blue pixels and the “photo-resonance” model could arrive at a dynamic ‘auto-enhance’ preset which recommends settings that provide warm tones.
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
Referring now to FIG. 1, illustrative cloud computing environment 150 is depicted. As shown, cloud computing environment 150 includes one or more cloud computing nodes 110 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 154A, desktop computer 154B, laptop computer 154C, and/or automobile computer system 154N may communicate. In addition, the cloud computing nodes 110 may include a “smart phone” or a digital camera equipped with a processor, memory, a camera, and GPS circuits and modules for location determination (not shown in FIG. 1). Nodes 110 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 150 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 154A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 110 and cloud computing environment 150 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
Referring now to FIG. 2, a set of functional abstraction layers provided by cloud computing environment 150 (FIG. 1) is shown. It should be understood in advance that the components, layers, and functions shown in FIG. 2 are intended to be illustrative only and embodiments of the invention are not limited thereto. As depicted, the following layers and corresponding functions are provided:
Hardware and software layer 210 includes hardware and software components. Examples of hardware components include: mainframes 211; RISC (Reduced Instruction Set Computer) architecture based servers 212; servers 213; blade servers 214; storage devices 215; and networks and networking components 216. In some embodiments, software components include network application server software 217 and database software 218.
Virtualization layer 230 provides an abstraction layer from which the following examples of virtual entities may be provided: virtual servers 231; virtual storage 232; virtual networks 233, including virtual private networks; virtual applications and operating systems 234; and virtual clients 235.
In one example, management layer 250 may provide the functions described below. Resource provisioning 251 provides dynamic procurement of computing resources and other resources that are utilized to perform tasks within the cloud computing environment. Metering and Pricing 252 provide cost tracking as resources are utilized within the cloud computing environment, and billing or invoicing for consumption of these resources. In one example, these resources may include application software licenses. Security provides identity verification for cloud consumers and tasks, as well as protection for data and other resources. User portal 253 provides access to the cloud computing environment for consumers and system administrators. Service level management 254 provides cloud computing resource allocation and management such that required service levels are met. Service Level Agreement (SLA) planning and fulfillment 255 provide pre-arrangement for, and procurement of, cloud computing resources for which a future requirement is anticipated in accordance with an SLA.
Workloads layer 270 provides examples of functionality for which the cloud computing environment may be utilized. Examples of workloads and functions which may be provided from this layer include: mapping and navigation 271; software development and lifecycle management 272; virtual classroom education delivery 273; data analytics processing 274; transaction processing 275; and “photo-resonance” model 276.
Referring now to FIG. 3, there is shown a block diagram illustrating a computer system 300 which may be embedded in a cloud computing node 110 in an embodiment. In another embodiment, the computer system 300 may be embedded in a “smart phone” capable of being connected to a network and which is equipped with a camera and a capability for determining location, e.g., a GPS transceiver. In yet another embodiment, the computer system 300 may be embedded in a conventional digital camera capable of being connected to a network and which includes a capability for determining location, e.g., a GPS transceiver. As shown, a computer system 300 includes a processor unit 302, a memory unit 304, a persistent storage 306, a communications unit 312, an input/output unit 314, a display 316, and a system bus 310. Computer programs such as “photo-resonance” model 276 are typically stored in the persistent storage 306 until they are needed for execution, at which time the programs are brought into the memory unit 304 so that they can be directly accessed by the processor unit 302. The processor unit 302 selects a part of memory unit 304 to read and/or write by using an address that the processor 302 gives to memory 304 along with a request to read and/or write. Usually, the reading and interpretation of an encoded instruction at an address causes the processor 302 to fetch a subsequent instruction, either at a subsequent address or some other address. The processor unit 302, memory unit 304, persistent storage 306, communications unit 312, input/output unit 314, and display 316 interface with each other through the system bus 310.
Referring now to FIG. 4, a flow chart of a machine learning process 400 for recommending location and content aware filter settings for taking photographs using a “photo-resonance” model in accordance with one or more embodiments. At 402, the system may aggregate photographs from a variety of data sources, e.g., http://www.image-net.org/ or from social media websites with crowdsourced feedback data. The system may also aggregate social media interactions (e.g., “likes”) from images in order to create an initial data set of images and social media feedback for analysis. Links to these images and the associated data may be stored as records in a database.
At 404, the system may assign human interaction, or resonance, scores based on the social media interactions from 402 for each image. The system may also use computer vision or existing convolutional neural network (CNN) trainers and classifiers such as MIT Places 365 to determine and classify the scene being displayed (and, if possible, geographic location) in each image in operation 404. The system may determine the geographic location of the online images either directly from associated image metadata, or through object recognition. Image location data will later be compared with a location of the real-time desired image to determine relevance in the calculation of recommended filter settings. In operation 404, the system may also extract metadata from images using common tools such as exifread in Python and read_exif in the R programming language. Standard photograph file formats such as JPEG (most commonly used in digital cameras and phone processors) or TIFF typically store this metadata as openly available EXIF data within the data file.
Various aspects of the disclosed embodiments require that a photographic image or an image in the field of view of a camera by classified by scene. A plurality of different scenes are contemplated. A “scene” may be defined by how the subjects in an image are framed, e.g., extreme wide angle, wide angle, full (head-to-toe of subject), medium angle, medium close up, close up, or extreme close up. A “scene” may be defined based on the camera angle with respect to the subjects, e.g., at eye level, high angle (camera looking down on subject), or low angle (camera looking up at subject), and the like. A “scene” may be defined based on visual elements in the frame, e.g., inanimate natural elements like trees, mountains, rivers, lakes, snow, rain, season, rocks, sand, grass, and flowers. Visual elements in a frame may include animate natural elements like dogs, cats, horses, or birds. Visual elements in a frame may include people. Visual elements in a frame may include man-made objects, like houses, buildings, cars, bicycles, walls, boats, etc. Visual elements in a frame may include iconic or widely recognizable man-made objects, like the Eiffel Tower, the carvings of U.S. Presidents at Mount Rushmore, S. Dak., the Washington Monument in Washington, D.C., or the Sleeping Beauty Castle at Disneyland theme park. A “scene” may be defined by its geographic location. Thus, a “scene” may be defined based on one or more of these shot types, visual elements, and geographic location. It should be appreciated that the possible visual elements is not limited to those listed in this paragraph.
Metadata extracted from image files may include geographic location, camera setting, time of day, day of year, and other pertinent data. Examples of the metadata collected from online images may include the aperture setting (expressed as an F-number) when the image was taken, the contrast setting when the image was taken, the digital zoom ratio used to record the image, which could be expressed as a decimal value or fraction or in text such as ‘off’ to specify that no digital zoom was used, the camera's exposure bias setting when the image was recorded, usually specified in stops, the exposure program used to record the image (e.g., aperture priority, shutter priority, etc), the exposure time used to record the image, usually specified in seconds as a whole number or a fraction (e.g., 1⁄5) or a decimal (e.g., 1.8), whether the flash fired when the image was taken, along with any potential special mode used such as “red-eye reduction” and the actual focal length of the lens, typically expressed in millimeters.
Further examples of image metadata include the GPS altitude relative to mean sea level where the picture was taken, where a negative value would indicate that the image was taken below mean sea level, the GPS latitude where the picture was taken, typically specified in degrees, minutes and seconds, in either the northern or southern hemisphere, the GPS longitude where the picture was taken, also usually specified in degrees, minutes and seconds, and either east or west of the prime meridian, the (equivalent) film speed when the image was taken, typically expressed using the ISO scale, the exposure metering mode used when the image was taken (e.g., average, spot, multi-spot), the rotation information stored in the image, usually set by the camera's orientation sensor to reflect the orientation of the camera when the image was recorded, the saturation of the image (typically normal, high or low), the type of scene capture program used by the camera (e.g., standard, night, portrait), the sharpness of the image (e.g., normal, hard or soft), the speed of the shutter when the image was taken, usually specified in seconds as a whole number or a fraction (e.g., 1⁄5) or a decimal (e.g., 1.8), the distance from the focal point to the subject, usually specified in meters as a whole number or a fraction (e.g., 1⁄5) or a decimal (e.g., 1.8) and the camera's white balance setting when the image was taken.
In addition, image metadata may include statistics for each of the image channels in a digital image. For example, average color values of pixels in each of the red, blue, and green channels of an RGB image may be provided. In addition to average value, other descriptive statistics such as standard deviation of color channel values may be provided. Metadata may include statistics concerning luma or luminosity of an image, such as average, standard deviation, and variance of luma values of an image. This list is not exhaustive, and the system may collect any metadata that is available about the images.
Lastly at 404, the system may associate the resonance score, GPS location, scene information and the appropriate image metadata collected above with specific photographs and store this together in a database 308 to be used as training data for the “photo-resonance” model.
At 406, the system may derive a “photo-resonance” model using the training data, which may be a multi-vector/multi-target regression model correlating emotions to various data factors from the metadata extracted in 404 including GPS location, scenes, time of day, time of year, color, hue and brightness. In various embodiments, the model may be a support vector machine (SVM). In various embodiments, the model may be a supervised learning model. The model may be used to classify a photograph that was not included in the training data according to resonance score. In other words, the model may predict a resonance score for a photograph having an unknown resonance score. The training data photographs may be ranked by their resonance scores, with only those highest ranked filter settings eventually becoming viable recommendations that will be presented to photographers in real time for a decision to accept the new settings or not. Photographs captured using recommended settings may be presented to others, e.g., in an online social media platform. If photographs with the accepted presets subsequently elicited or evoked positive emotions from the other viewers, those camera settings would be promoted for that scene or type of photograph and used to make changes to the “photo-resonance” model. Presets which are “liked” on average more than similar photographs taken with different camera settings may be promoted up in the results ranking data store. Presets that perform lower on average than similar photographs taken with different camera settings may be demoted in the ranking. The higher-ranking presets may be applied more often to the photographs with the expectation of generating more “likes” (positive emotions), while lower-ranking presets may be changed and retried until the performance improves. The ranked results may be tagged based on the classification of the scene analyzed and GPS location.
In various embodiments, the ability of the model to predict a resonance score for a photograph having an unknown resonance score may be validated. If the model fails to predict resonance scores for images generally or images of a particular scene type, the model may be refined, revised or updated by creating a control or test group of frequent online users who have a threshold number of views or interactions on social media. The system may then apply a random set of auto-enhance presets to certain “test” images and feed these back to the group of human testers on social media to learn the changes in emotions under different camera settings or simulated camera settings. If a particular test image using a first setting was “liked” by more people than the same test image using other settings, the first auto-enhance presets may be promoted. The promotion may be done by adding a positive reward value for each instance that the auto-enhance presets are accepted by people. Those images with fewer “likes” may be scored with a negative penalty value and may be removed or changed to create a new auto-enhance preset, which may be shown to the test group again. The expected likelihood of a viewer choosing an image with a particular auto-enhance preset, from the multiple possible auto-enhance presets, would be proportional to the total positive reward value minus the total negative penalty value. In another embodiment, the system may randomly choose or create a new or altered auto-enhance presets and show those to the test group or a subgroup of it. The results may be used to improve the “photo-resonance” model with additional training data.
Operation 408 may be performed in response to a user preparing to take a photograph. The current image properties such as GPS location and scene type may be extracted by the system before the image is clicked using computer vision and the current filter or other device settings may also be determined by the system. The “photo-resonance” model may be applied to create a dynamic auto-enhance preset, which may recommend to the user certain changes to properties such as color, brightness or contrast to bring the image closer to those images that the model has determined to elicit or evoke more positive emotions. In an embodiment, the recommended settings may be shown on the device by repositioning the filters within the UX with the most popular at the top. In another embodiment, the filters on the device could be reconfigured to preemptively show the most popular settings at the expense of the current ones. The user could then choose to accept or reject the recommendations from the “photo-resonance” model.
Once the user has selected their desired filters and other settings and has taken their photograph, the “photo-resonance” model may record the user's choices in accepting or rejecting the recommended settings, as well as the actual settings that were used for the photograph. A signal or indication corresponding with user emotions, e.g., a “like” or other input, for images which use the dynamic auto-enhance preset may be fed back as additional training data into the “photo-resonance” model. The “photo-resonance” model may also record social media emotional data for the settings that were used if they were not recommended by the model.
In various embodiments, derivation or refinement 404 of the “photo-resonance” model may be performed on one or more server computers running in a cloud. Modules of the photo resonance model may then be deployed to smart phones or cameras, which may gather environmental and location parameters to use model to recommend camera settings. In an embodiment, the photo resonance model could be provided as software as a service (SaaS).
