Rate-Distortion Optimization for Internet Video Summarization and Transmission

Abstract

The goal of video summarization is to generate a shorter video sequence of a lengthy original sequence using only the key frames of the original sequence. We consider a video summarization scheme that generates a video summary that can be transmitted over an unreliable network such as the Internet with minimum distortion of the original video. We consider two methods of distortion measurement in our optimization scheme, and we apply the methods to a scenario in which feedback is available with the possibility of retransmitting lost packets. Simulation results showing the effectiveness of using the proposed schemes are presented
