For frames involving an abrupt scene change, almost all macroblocks are encoded using intramode in H.264/ AVC. Before encoding such frames, one must first determine whether a scene has changed to perform the appropriate rate control. Since the computation load of H.264/AVC is heavy, a more cost-effective algorithm for detecting scene changes Is necessary for real-time operations. We propose such an algorithm for high-motion video, and the results show that the proposed algorithm reduces the computational load by 37 to 92% from existing algorithms.
