Interframe finite-state vector subband coding (VSC) scheme for very low bit rate (VLBR) video coding

摘要: Vector subband coding (VSC) has been shown to be a promising technique for very low bit rate (VLBR) video coding. Good performance of VSC is achieved because the vector filter bank used in preserves intra- correlation while reducing inter-band and inter-vector correlations. Application VLBR with intra-frame only reported previously. In this paper, we describe an inter-frame scheme To reduce redundancy, most popular motion compensated prediction. This effective pixel-based schemes such as ones various standards. However, it not efficient when vector-based schemes. Therefore, instead predicting pixel values prediction difference, proposed new vectors subbands previous frame predict corresponding current frame. It that promises good coding.© (1995) COPYRIGHT SPIE--The International Society Optical Engineering. Downloading abstract permitted personal use only.
