A tree structured Bayesian scalar quantizer for wavelet based image compression

Multiresolution image decompositions (e.g., wavelets), in conjunction with a variety of quantization schemes, have been shown to be very effective for image compression. Recently, several promising tree-structured quantization schemes that exploit the correlation across scales have been proposed. In this paper, we present an image compression algorithm based on a multiresolution Markov random field model used to model the correlations of wavelet coefficients across the scales. We also present experimental results obtained using the algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
