Since their invention, computers have always efficiently replaced manual labour. Although they can be programmed to do an endless task over and over their lack of human senses restricts their usability. If, perhaps, computers were given the ability to see like humans, they could do more than just see. Computers can be customized to process what they see based on the commands given to them. They can process, analyse and recover desired data from the video input in a short time, which is otherwise tiring for a human. This concept is called video analytics.
