A New MPEG Video Stream Cut Detect Algorithm Based on Motion Vector
() Abstract
A new fast MPEG video scene cut detection algorithm is proposed in this paper. The similarity of a frame to it's predictive frames was calculated based on corresponding motion vector in it's MPEG stream and was further normalized. Then, a scene cut can be detected according to the normalized similarity. Test results have shown that this method greatly increased the speed and accuracy of MPEG video scene cut detection.
