Image pyramid coding with multirate entropy-constrained pairwise nearest neighbor codebook design

摘要

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 design technique with constrained alphabet. Results of coded image pyramids of the present algorithm are comparable to the ECPNN design technique.!13
