摘要

介绍了一种对MPEG VIDEO码流中场景切换点进行高速检出的新方法，在计算各帧相对于预测帧的类似度之后进行了类似度的归一化，降低了cut检出算法的复杂度，提高了检出的速度。

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.
