摘要：

Image processing is a method of analyzing and manipulating the digitized image to reduce noise and to improve its quality. It usually refers to digital image processing, but image processing can also be done for optical and analog types. The input is an image which can be either a photograph or video frame while the output can either be an image or a set of characteristics of an image.The analysis of an image requires techniques that can identify colors, shades etc. we present a method that focuses totally upon tampering detection and to provide authentication when a video is transmitted from one user to another. It also concentrates on reducing noise distortion. This is made possible by means of using modified QDCT and by embedding watermark signals.
