Abstract:Because of the interference with kinds of noise, the quality of video frame was degradation in the communication process, Video frame degradation should be restored to ensure high quality communication.In this paper, the image restoration principles of Inverse filtering and Wiener filtering(minimum square error filter) were analyzed with Image degradation in frequency domain, the two image restoration technology was compared with implemented in VC++ programming. The experiment result was showed that the two filter techniques had own characteristics. The algorithm of inverse filtering was sample, it is better to restore for small image degradation ;however,the degraded image and the little signal to noise was received apparently recovery by Wiener filtering.
