Abstract

In this paper, we investigate the rate-distortion (R-D) performance of the embedded wavelet coder and the frame dependency between the reference frame and the predictive frame. Then, according to the rate-distortion model and the frame dependency to solve the rate control problem to a bit allocation problem for each frame. Experimental results show that the superior performance of the embedded wavelet video coder with the proposed rate control scheme.
