These days, image processing isn't just a fringe field in computer science. It is already playing an important role in the real world in several fields. For example computer science, optics, mathematics, surface physics and visual psycho-physics. Computer Vision, as a whole is used in finger-print and face detection, argument reality, microscopic imaging, feature extraction, remote sensing, meteorology, optical sorting etc.

In this short documentary, we take you through image processing in the modern world, giving you a short overview. We also tell you the applications of image processing in modern world. We also categorize image processing, as well as explaining the challenges of image processing.
