Scene Change Detection Using Motion Vectors and DC Components of Prediction Residual in H.264 Compressed Videos

摘要

An algorithm is proposed to detect abrupt and gradual scene changes in H.264 compressed videos. In H.264, the inter prediction in the encoding process generates the DC component of the prediction residual. In this paper, we use the DC component of inter prediction residuals as well as motion vectors to detect scene changes. Using the proposed algorithm, we can detect scene changes for H.264 compressed videos more effectively, as demonstrated by simulations.
