Key Frame Extraction from Online Video Based on Improved Frame Difference Optimization

摘要：

　　As the fast development of network and multimedia technology,there are mass of videos on the Internet.The problem of how to browse the large volume of video data is urgent to be solved.Key frame extraction is a very important technology in online video retrieval and video abstraction.Efficient key frame extraction can boost the development of video browsing technology.In this paper,we first review some commonly-used key frame extraction technology,and then propose a improved key frame extraction algorithm,which measures the similarity of two adjacent framescontents in terms of the information of frame difference and extracts key frames after optimizing the frame difference.The experiment results show that the proposed algorithm can extract key information from online video efficiently,and has a good description in the aspect of motion of the camera lens.
