A new method based on twi-difference algorithm and motion-matching of the potential shots algorithm for video abrupt shot change detection

摘要

The abrupt shot change detection is a basic and important technology in content-based video retrieval. Some basic algorithms, such as the pixel-matching algorithm, the histogram algorithm, used to detect abrupt shot change in digital video have existed. But existing algorithms can't eliminate the influence of the video movement and were easily affected by the shakes of the shots. When much video movement or shakes existed, existing algorithms can't perform well. In this paper, a new method is proposed, the proposed method consists of two new algorithms: twi-difference algorithm and motion-matching of the potential shots algorithm. The twi-difference algorithm can eliminate the influence of the video movement on the shot change detection. The motion-matching of the potential shots algorithm can reduce the influence of the video shakes. Experimental results have showed that the new method performs well both in recall and precision.
