Computer vision is an engineering field where the objective is to create programs that can extract meaning from images. According to an urban legend, computer vision first started in the 1960s when Professor Marvin Minsky from MIT assigned a summer project to a group of undergraduates, with the requirement that they should attach a camera to a computer and to have the computer describe everything that it sees. The project was expected to be completed in just one summer. Needless to say, it wasn't completed within that summer as computer vision is an extremely complex field that scientists are continuously working on even today.

Early progression in computer vision was modest. In the 1960s, researchers started by creating algorithms to detect shapes, lines, and edges in photographs. The following decades saw the evolution of computer...
