摘要:
A GOP level video scene change detection algorithm in H.264/AVC baseline profile compression domain is pro-posed. The algorithm is based on intra prediction modes, motion vectors and macroblock coding types which can be extracted from H.264/AVC baseline bitstream. Three new criteria, the difference of chroma prediction modes based on sub-block, the accumulative motion amount and the accumulative intra coding macroblock amount, are proposed. Experimental results show that compared with another typical GOP level method, the proposed algorithm can achieve better performance.
