Journal ArticleDOI
Conditional entropy-constrained vector quantization: high-rate theory and design algorithms
TL;DR: The performance of optimum vector quantizers subject to a conditional entropy constraint is studied and a new performance bound is compared and shown to be consistent with bounds derived through conditional rate-distortion theory.
Proceedings ArticleDOI
Adaptive transform tree coding of images
TL;DR: In encoding simulations the adaptation with smoothing and quantization gave better performance with a block size of 16 at lower search intensity and with more uniformity and less blocking effect, but with a savings of search and computational complexity.
Proceedings ArticleDOI
Tree coding of image sub-bands
S. Nanda,William A. Pearlman +1 more
TL;DR: It is proved that optimal coding of image subbands achieves the ultimate rate-distortion performance for Gaussian sources with squared-error distortion.
Journal ArticleDOI
Correction to Region-Based Wavelet Coding Methods for Digital Mammography
Proceedings ArticleDOI
Texture coding using a Wold decomposition model
TL;DR: An algorithm for estimating and coding the texture model parameters is presented, and it is shown that the suggested algorithm yields high quality reconstructions at low bit rates.
