In order to get the best mode, H.264 computes the cost of every mode for each block by RDO (rate distortion optimization) technique, but it increases a high computational complexity .This paper combines Pan's fast algorithm and an efficient fast mode decision for intra prediction is proposed. First, the intra prediction's types are decided by whether a block is smooth. Second, the Pan's fast algorithm...
Pattern-based video coding (PVC) has already established its superiority over recent video coding standard H.264, at low bit rate because of an extra pattern-mode to segment out the arbitrary shape of the moving region within the macroblock (MB). To determine the pattern-mode, the PVC however uses three thresholds to reduce the number of MBs coded using the pattern- mode. By setting these content-sensitive...
