Self-adaptive Smooth Correct or model(SASC) is proposed for the restoration of the blotch. An algorithm

named bidirectional matching

is designed for motion estimation in the restoration specially. Without making judgment

this algorithm can detect the suitable motion direction on different situations of noise occupation. The Weber ratio is used to make the noise detector to be sensitive and accurate and the bulge algorithm is used to dealwith the edge-problem of the noise. Experimental results using video sequence with real film have demonstrated the availability of the method.
