Improved Intra-coding Methods for H.264/AVC

Improved Intra-coding Methods for H.264/AVC

The H.264/AVC design adopts a multidirectional spatial prediction model to reduce spatial redundancy, where neighboring pixels are used as a prediction for the samples in a data block to be encoded. In this paper, a recursive prediction scheme and an enhanced (block-matching algorithm BMA) predictio...
