| 摘 要： | 有特定视频内容（例如电视电影）的自动描述算法还不够完善。本文针对已有算法的缺点，在对视频提取的关键帧的基础上。提出按层次的关键帧分组．组内比较．分块比较．加权运算等改进算法。实验表明，通过图像分块可以保留颜色的空间信息，通过关键帧分组比较．以及先中间子块比较，可以提高运算速度。

| Abstract: | There is work to be done in the algorithm for automatic describing contents with particular video frequency,e.g.,TV film.To cope with the shortcomings of conventional algorithms,stepwise algorithms' modification is presented.It includes extracting the video key frames and dividing into groups,comparison within the groups,block comparison,and weighted operation. Experiment reveals that color space information is preserved effectively by dividing the image into different blocks.The comparison within groups and the first comparison of the middle block algorithm improve the speed of operation. |
