Video Pause Detection Using Wavelets

As the volume of digital video captured and stored continuesto increase, research efforts have focused on contentmanagement systems for video indexing and retrieval applications.A first step in generic video processing is shot boundary detection. This paper addresses a novel algorithm for abrupt shot (cut/pause) detection - especially on frames with similar statistics - based on the wavelet transformand content entropy. The algorithm has been successfullytested on some video categories including sport and live videos. Its quantitative performance has been comparedto other known methods including pixel, histogram, frequency domain and statistics difference. In each test, the proposed wavelet method outperforms the others.
