<title>Image pyramid coding with multirate entropy-constrained pairwise nearest neighbor codebook design</title>

Abstract

A new algorithm for multirate vector quantization is used for coding image pyramids. The algorithm, called alphabet-and entropy-constrained pairwise-nearest-neighbor (AECPNN), design codebooks choosing sub-codebooks from a large generic codebook. The algorithm is the natural extension of the ECPNN [1,2] design technique with constrained alphabet. Results of coded image pyramids of the present algorithm are comparable to the ECPNN design technique. 0-8194-081
