Abstract
The coding efficiency of AVS-P2 for the video sequences, which have many scene changes, is generally low. If the scene changes are taken into consider for video compression, the encoding performance can be improved. An adaptive group of picture (GOP) size structure based on scene change is proposed here in AVS-P2 encoding. With a little additional computation, the proposed algorithm has improved the PSNR by 0.15~2.2 dB in the video sequences with scene changes.
