In general, Imaging or image processing is any form of signal processing for which the input is an image, such as a photograph or Image or video frame; the output of image processing may be either an image or, a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.

Stereo Imaging and 3D Imaging is getting popular with growing needs from different avenues that include medical Imaging and machine vision.
