Improved fast video summarization method and system

The invention discloses an improved fast video summarization method and system and belongs to the digital image processing technology and computer vision technology field. According to the method and system of the invention, the summarization system is innovatively improved in that frequency-relatively slowed down background update, frame skip type target extraction and collision type target ordering are adopted, and therefore, higher-level requirements of today's society for the summarization system can be satisfied. The improved fast video summarization system not only has a moving target accurately locking ability of an original video summarization system, but also can perform summarization more quickly and greatly compress video time, and therefore, storage pressure can be reduced, and working time can be decreased.
