Method, post-processing filter, and video compression system for suppressing mosquito and blocking artifacts

摘要

The visibility of mosquito and blocking artifacts in a video compression system (200) are effectively suppressed by calculating a post-processed pixel intensity. A post-processed pixel intensity is determined (100) using a predetermined noise variance, a predetermined autocorrelation coefficient, and a local neighborhood of pixels that includes a plurality of previously post-processed pixel intensities and a plurality of original pixel intensities. This eliminates the dependency on local signal and noise power estimates.
