IMPROVING H.264/AVC INTER COMPRESSIONWITH MULTISCALE RECURRENT PATTERNS

In this paper we describe the ongoing work on a new par-adigm for compressing the motion predicted error in a video coder, referred to as MMP-Video. This new coding algorithm uses the MultidimensionalMultiscale Parser image coding al-gorithm to encode the residue error, in a H.264/AVC based video coder. MMP has shown to perform very well as a universal still image coding method, particularly when it is combined with Intra prediction schemes. In addition, previously published preliminary results have also presented MMP as a promising video coding method. In this paper, we propose new dictionary updating tech-niques for MMP-video. Along with other functional opti-mizations, these techniques allow for a significant improve-ment in the encoder performance. Thus, we were able to achieve considerable gains over H.264/AVC for B slices, spe-cially formedium and high bit-rates, while maintaining equiv-alent performance for the P slices.
