An orientation normalized vector quantizer for flow-like image coding

Abstract

A new vector quantization image coding scheme called orientation normalized vector quantizer (ONVQ) is presented in this paper. During the encoding process, the orientation freld of an image is fist calculated and recorded wing quad-tree data structure; then, the image is partitioned into digitalized round blocks. These round blocks are normalized to… (More)
