An Approach of Key Frame Extraction Based on Mutual Information

Key frame extraction is one of fundamental processes in video analysis and content-based video retrieval. Key frame can dramatically reduce the data of the video indexing, and provides a framework for video abstraction and retrieval. This paper briefly discusses the existing approaches, It presents a new approach for key frame extraction based on mutual information. Experimental results show that the approach is computationally simple and able to adapt to the visual content.
