Abstract

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 VSC preserves intra- vector correlation while reducing inter-band and inter-vector correlations. Application of VSC to VLBR video coding with intra-frame coding only has been reported previously. In this paper, we describe an inter-frame VSC scheme of VLBR video coding. To reduce inter-frame redundancy, the most popular technique is motion compensated prediction. This technique is effective in pixel-based coding schemes such as the ones used in various video coding standards. However, it is not very efficient when used in vector-based coding schemes. Therefore, instead of predicting pixel values and coding the prediction difference, the proposed new technique used the vectors in the vector subbands of the previous frame to predict the vectors in the corresponding vector subbands of the current frame. It is shown that such an inter-frame coding scheme promises good performance for VLBR video coding.
