Abstract

We propose a new algorithm to detect shot change, which is necessary in retrieval of video data. In order to solve the problems of abrupt brightness change and similar brightness between frames in the typical shot change methods, we propose the hi-polarity histogram method which takes into account the distribution and magnitude of brightness changes in consecutive frames. We evaluate our algorithm with compressed and uncompressed video data and demonstrate its improved performance.
