Rate-distortion model for motion prediction efficiency in scalable wavelet video coding
2009
2009 17th International Packet Video Workshop
A rate-distortion model for motion prediction efficiency in scalable wavelet video coding is proposed in this paper. The Lagrangian multiplier is widely used to solve the ratedistortion optimization problems in video coding, especially on mode decision and rate-constrained motion estimation. Different from the non-scalable video coding, the scalable wavelet video coding needs to operate under multiple bitrate conditions and it has an open-loop structure. Therefore, the conventional
