Research on scene change detection algorithm based on H.264/SVC

Scene change detection is a key technique of video coding, it has an important impact on the video quality. This article analyzed and compared three conventional algorithms of scene change detection, aiming at the shortcoming of scene change detection algorithm based on image complexity, presented an improved algorithm of scene change detection based on image complexity combining with G012 rate control standard. Experimental results show that the improved algorithm could correctly detect sudden scene change and gradual scene change between GOP, overcomes the problem which the original algorithm could not detect the gradual scene change between GOP, and effectively enhances detection accuracy of scene changes in video sequences.
