Paper Abstract

The comparison of video sequences at low bit-rates is object of an intense study. For high compression ratios, standard techniques produce noticeable artifacts in the reconstructed images. This article proposes a method for the post- processing of motion compensated hybrid coded video data. The technique uses a stochastic regularization approach which can be implemented with a simple and fast iterative algorithm. The approach has been applied to color video sequences produced by h.261 and h.263 standard compression methods. The post-processed sequences are aesthetically superior to the sequences obtained using the standard technique.
