Artificial Intelligence (AI) is an advance branch of science that studies the process of human thinking and attempts to apply the knowledge to simulate the same process in machines.
Nanorobots, robots of microscopic scale of about nanometers, are based on hypothetical nanotechnology engineering to build machines that are microscopic in size. Building robots that would be so small that many of them could be lined across the width of a human hair is a big challenge to achieve.
A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the ways to do this is by comparing selected facial features from the image and a facial database.
