Reduction of coding artifacts in low-bit-rate video coding
R.L. Stevenson · 2002
The compression of digital video data has many applications in the transmission and storage of video sequences. For moderate compression ratios there are many techniques which can provide satisfactory performance. For high compression ratios, however, typical compression techniques produce noticeable artifacts in the reconstructed video. This paper proposes a technique for the post-processing of motion-compensated compressed video data. The technique utilizes a stochastic regularization approach which can be realized using a simple and fast iterative computational algorithm. The approach has been applied to the post-processing of color video sequences and yields good results.
