摘要

To clearly visualize the video structure and provide a user-friendly video content review and retrieval system, we first apply total variation (TV) metric to video shot segmentation and propose a novel video visualization method in this paper. Firstly, video data visualization design principles are proposed based on the analysis of video data characteristics. Secondly, a TV metric is proposed to measure the distance between two video frames. Then, video shots are detected by TV metric, video key frames are extracted by k-means algorithm, and similar shots are retrieved based on frame dominant color. Finally, according to the proposed video visualization design principles, a hierarchical radial video visualization method is presented. Experimental results show that the proposed video visualization method can express the video content and the whole structure directly and clearly.
