基于时空切片的关键帧提取研究
Key Frame Extraction Based on Space-time Slice
摘要
Abstract
Key frame extraction is an important part in video retrieval and video abstraction.Existing methods are lack of spatio-temperal analysis and not consistent with human perception,therefore a new key frame extraction method was proposed in this paper.Firstly,space-time slice of a shot is extracted,and then K-means clustering is made on the space-time slice,at last,key frames are extracted in every cluster according to the video temporal continuity.As the experimental results showed,this method can capture the main content and exhibit excellent visual continuity and low repetition,which is consistent with human perception.关键词
