发明名称 Video signal processing
摘要 In video scratch repair, scratches are treated as additive pedestals which are constant or slowly changing along the scratch. For a given picture, these pedestals are estimated and subtracted from the video input to reveal original picture detail. The pedestal can be estimated by heavily filtering along the direction of the presumed scratch, the output of a prior art scratch detector.
