Adaptive entropy-constrained residual vector quantization
Faouzi Kossentini, Mark J. T. Smith · IEEE Signal Processing Letters · 1994
Entropy-constrained residual vector quantization (EC-RVQ) is a relatively new VQ method that was shown to be capable of excellent rate-distortion performance. The paper investigates the incorporation of adaptivity into the EC-RVQ framework for application to image coding. Experimental results show that the dynamic nature of the implementation leads to a noticeable improvement in coding quality as well as improved robustness.>
