The imitation and reproduction of human vision by computers is the most brief definition of this field. It provides inference from an object, text, or a three-dimensional model. The grouping of elements in an image offers a wide range of possibilities, such as determining and searching the angle and position of the camera that captures the image.
In order to study human biological vision, both the vision process of the eye and the perception process of the brain must be interpreted. Much progress has been made to develop a system that can mimic vision, but there is still a long way for science to fully understand the brain's perception process.
Optical character recognition and face recognition systems, which have been available in smartphones in recent years, are indicative of progress in this area.
