Research on the Technology of Video Key Frame Extraction Based on Clustering

The video key frame extraction technology is one of the important parts of content-based video retrieval. And the mainstream of key frame extraction is the algorithm based on clustering. The basic idea is: the video frames are grouped in accordance with the correlation of the visual content by clustering, and then we extract the most representative frame from each group as a key frame. In this paper, several common key frame extraction algorithms based on clustering are elaborated along with their advantages and disadvantages.
