The goal of [computer vision](https://www.ibm.com/topics/computer-vision#:~:text=Resources-,What%20is%20computer%20vision%3F,recommendations%20based%20on%20that%20information.) is to mimic human visual perception and understanding of the world, which is a complex process that involves multiple levels of abstraction and interpretation. Computer vision algorithms typically involve image processing, feature extraction, object recognition, and [machine learning](https://www.techtarget.com/searchenterpriseai/definition/machine-learning-ML)techniques to achieve this goal.

Let’s get started, 

## What is computer vision?

[Computer vision](https://www.ibm.com/topics/computer-vision) is a field of [artificial intelligence](https://www.techtarget.com/searchenterpriseai/definition/AI-Artificial-Intelligence#:~:text=Artificial%20intelligence%20is%20the%20simulation,speech%20recognition%20and%20machine%20vision.) and [computer science](https://www.britannica.com/science/computer-science) that deals with how computers can be made to interpret and understand visual information from the world, in the same way, that humans do. This involves processing and analyzing images and videos to extract information and make decisions based on that information.

[Applications](https://online.glyndwr.ac.uk/what-are-computer-applications/) of computer vision include image recognition, object detection, facial recognition, image segmentation, and autonomous vehicles, among others. The techniques used in computer vision include deep learning, pattern recognition, computer graphics, and image processing. The goal of computer vision is to enable computers to gain a high-level understanding of the visual world and perform tasks such as recognizing objects, tracking motion, and analyzing scenes.

## What are the types of AI computer vision?

There are several types of AI computer vision, including:

- [Image classification](https://viso.ai/computer-vision/image-classification/): categorizing images into predefined classes based on their visual content.
-  [Object detection](https://en.wikipedia.org/wiki/Object_detection): detecting and localizing objects within an image.

- [Semantic segmentation](https://datagen.tech/guides/image-annotation/semantic-segmentation/): segmenting an image into semantically meaningful regions and classifying each region.

- [Object tracking](https://blog.roboflow.com/what-is-object-tracking-computer-vision/#:~:text=Object%20tracking%20is%20a%20computer,multiple%20objects%20in%20an%20image.): detecting and tracking objects across multiple frames in a video.

- [Pose estimation](https://datagen.tech/guides/face-recognition/pose-estimation/#:~:text=Pose%20estimation%20is%20a%20computer,is%20located%20in%20an%20image.): estimating the position of objects and their parts within an image.

- [Image generation](https://www.crayon.com/resources/insights/AI-Image-Generation-Reshapes-the-Creative-Industry/): synthesizing new images based on a given input.

- [Image restoration](https://en.wikipedia.org/wiki/Image_restoration): restoring degraded images to a visually plausible state.

## What is an example of computer vision?

An example of computer vision is face recognition technology, where a computer algorithm is trained to identify and match human faces in digital images and videos. This technology is widely used in various applications such as security systems, photo organization and tagging, and personal identification for access control. Another example is self-driving cars, which use computer vision to understand their environment and make decisions about navigation.

## What are the main features of computer vision?

Computer vision is a field that aims to enable computers to interpret and understand the visual world in the same way that humans do. Some of the main features of computer vision include:

- [Image/Video Processing](https://www.cs.ucf.edu/research/image-and-video-processing/#:~:text=Image%20and%20Video%20Processing%20addresses,%2C%20robots%2C%20and%20autonomous%20systems.): techniques for transforming, filtering, and enhancing visual data.

- [Recognition](https://www.techtarget.com/whatis/definition/object-recognition): the ability to identify objects within an image or video frame.

- [Scene Understanding](https://www-sop.inria.fr/members/Francois.Bremond/topicsText/sceneUnderstanding.html#:~:text=Scene%20understanding%20is%20the%20process,through%20a%20network%20of%20sensors.): understanding the context of an image, including recognizing and locating objects, as well as estimating their relative positions and scales.

- [Image/Video Segmentation](https://encord.com/blog/image-segmentation-for-computer-vision-best-practice-guide/#:~:text=Image%20segmentation%20is%20a%20computer,digital%20image%20into%20several%20components.): dividing an image or video into regions or segments, each of which corresponds to an object or a part of an object.

- [Motion Analysis](https://en.wikipedia.org/wiki/Motion_analysis#:~:text=Motion%20analysis%20is%20used%20in,information%20based%20on%20the%20apparent): tracking the motion of objects in a sequence of images or video frames.

- [3D Reconstruction](https://en.wikipedia.org/wiki/3D_reconstruction#:~:text=In%20computer%20vision%20and%20computer,rigid%20or%20spatio%2Dtemporal%20reconstruction.): creating a 3D model of a scene from multiple 2D images or video frames.

- [Deep Learning](https://aws.amazon.com/what-is/deep-learning/#:~:text=Deep%20learning%20is%20a%20method,produce%20accurate%20insights%20and%20predictions.): use of deep neural networks to perform tasks in computer vision, such as object recognition and segmentation.

## What is the advantage of computer vision?

Computer vision allows for the automatic extraction of information from visual data, enabling tasks such as image recognition, object detection, and scene understanding. The advantage of computer vision is that it can automate processes that would otherwise require human input and enable new forms of human-computer interaction and information analysis. Additionally, computer vision can also be applied in various fields such as medicine, self-driving cars, and security, among others, improving efficiency and accuracy.

## How are computer vision and artificial intelligence AI related?

Computer vision and AI are closely related because computer vision is often used as a subfield of AI to give machines the ability to interpret and understand visual data from the world, like images and videos. AI [algorithms](https://www.techtarget.com/whatis/definition/algorithm) are then applied to this data to make decisions, classify objects, detect patterns, and perform tasks such as image recognition, object detection, and facial recognition. In essence, computer vision provides the raw visual data for AI to process and make sense of, and AI provides the computational power and decision-making capability to turn this data into useful information.

## What language is used for computer vision?

Several programming languages are commonly used for computer vision tasks, including:

- [Python](https://www.learnpython.org/): it’s a popular choice due to the availability of many libraries, such as [OpenCV](https://en.wikipedia.org/wiki/OpenCV), [TensorFlow](https://www.tensorflow.org/), and [PyTorch](https://www.simplilearn.com/what-is-pytorch-article).

- [C++](https://www.w3schools.com/cpp/): it’s fast and efficient, making it a good choice for real-time computer vision applications.

- [Matlab](https://en.wikipedia.org/wiki/MATLAB): it’s widely used in academia for computer vision research and has a strong toolbox for image processing.

- [R](https://en.wikipedia.org/wiki/R_(programming_language)): it’s used for statistical analysis and has packages for computer vision tasks.

Ultimately, the choice of programming language depends on the specific requirements of the project and the developer’s experience and preference.

**Conclusion**

Computer vision is a branch of artificial intelligence that deals with enabling computers to interpret and understand visual information from the world around them. It involves processing and analyzing images and videos to extract meaningful insights and make decisions based on them.

As artificial intelligence continues to advance, computer vision will become increasingly important for enabling machines to interact with the world in more intelligent and intuitive ways.
