Computer vision is the automatic analysis of images and videos by computers in order to
gain some understanding of the world. Computer vision is inspired by the capabilities of the
human vision system and, when initially addressed in the 1960s and 1970s, it was thought to
be a relatively straightforward problem to solve. However, the reason we think/thought that
vision is easy is that we have our own visual system which makes the task seem intuitive to
our conscious minds. In fact, the human visual system is very complex and even the estimates
of how much of the brain is involved with visual processing vary from 25% up to more
than 50%.
