Efficient wavelet coding of motion compensated prediction residuals

In the coding of motion compensated prediction residuals, the competitiveness of wavelet coding relative to DCT coding is still an open issue. This paper describes an efficient and effective entropy coding strategy for the compression of wavelet transformed, motion compensated prediction residuals. Without the use of arithmetic coding, the proposed coder achieves competitive or better rate-distortion performance in comparison with H.263+, which uses DCT/runlength coding of the prediction residual. Moreover, the proposed coder furnishes better perceptual quality. The use of reasonably sized, static variable-length-codes in the proposed coder also helps to maintain low computational complexity and good error resiliency.
