Research on Robust and Efficient of Shot Change Detection in Video Retrieval
Abstract:Shot change detection is the basis of video retrieval, and its robust and efficient directly affect the precision of video retrieval. However, few take problems of robust and efficient into account. This paper reviews some recent solution methods. First, multi-threshold and adaptive threshold methods are introduced to improve robust. Second, the methods of compression algorithm and color space conversion are given to enhance efficient of shot change detection.
Keywords: video retrieval robust shot change detection adaptive threshold
