Rate control strategy for embedded wavelet video coders

摘要

An investigation into the use of rate-control strategies for embedded wavelet video encoders is presented. It is shown that the best model for the rate/spl times/distortion (R-D) curve of these encoders is piecewise linear. Also, an effective iterative procedure is proposed for dealing with the problem of frame dependency, which yields improved rate/spl times/distortion results.
