A computer vision system is a branch of AI in which computers and systems can obtain meaningful information from images, videos, and other inputs – and to take actions or make recommendations based on it. Computer vision is the capability of computers to see, observe, and understand as AI enables them to think.
Computer vision is much like human vision, except that humans have an advantage. A lifetime of context enables the human sight to tell objects apart, how far away they are, if they are moving, and if there is something wrong with an image.
AI in computer vision –
Computer vision combines Artificial Intelligence (AI) with different functionalities: analyzing human postures and movements, tracking humans and vehicles for data collection, analyzing videos with high-tech CCTV cameras to identify people, detecting diseases, and identifying objects for autonomous vehicles.
A computer vision system uses cameras, data, and algorithms rather than retinas, optic nerves, and the visual brain to train machines to perform these duties in a relatively short time. The ability of a system to inspect products or observe production assets can rapidly surpass human capabilities due to its ability to analyze thousands of products or processes at a time, detecting and reporting defects that may not be observed by humans.
Computer vision uses machine learning (ML) to teach computers to interpret and comprehend the visual world. Machines can now effectively detect and classify all kinds of items using digital photos from cameras and videos combined with deep learning algorithms.
There are some processes involved in AI computer vision –
- Image acquisition – Image acquisition helps in the conversion of analog data into a computer-readable format, like a series of zeros and ones. Digital cameras, webcams, and a range of other instruments are used to create datasets.
- Image processing – It entails extracting geometric elements from an image using modern applied mathematics techniques also including segmentation, classification, edge detection, and feature identification and matching.
- Image analysis and understanding – Enhanced algorithms are used in this process to undertake deep data analysis for 3D scene mapping, object tracking, and recognition. This analysis aids decision-making even more.
Computing vision refers to the way computers learn to understand the visual world by processing images and videos. It aims to replicate and automate tasks for which the human visual system is capable. Some examples of Computer Vision are –
- Cloud-based learning services make pre-built learning models available, as well as ease computing resource demands.
- Application programming interfaces (APIs) allow users to connect to the services and develop computer vision applications.
- When an image is seen, an image classification system can recognize it as a dog, an apple, or a face. It can accurately identify whether a particular image belongs to a specific class. A social network firm, for example, would want to utilize it to automatically detect and separate problematic photographs shared by users.
- Object tracking is the process of following or tracking an object after it has been detected. This task is frequently carried out using sequenced photos or real-time video streams. For example, autonomous vehicles must not only identify and detect items like pedestrians, other automobiles, and road infrastructure but also track them in motion to avoid crashes and follow traffic laws.
- Content-based image retrieval uses computer vision to explore, search, and recover images from massive data sets based on the images’ content rather than metadata tags. This task could include automatic image annotation, which would take the role of manual image tagging.
