A FAST MACROBLOCK MODE SELECTING METHOD BASED ON SPATIAL-TEMPORAL CORRELATION FOR H.264

摘要

H.264 is the latest international video coding standard. It adopts tree-structure macroblock partitions in motion-compensated coding modes to improve coding performance. This technology searches all available modes, so the computational cost increases linearly with the number of the allowed modes. In this paper, a fast macroblock mode selecting method based on spatial-temporal correlation for H.264 was proposed. This method efficiently reduces the computational complexity while keeping similar rate-distortion performance and can combine with other fast mode selecting algorithms to further reduce the computational complexity.
