Nearly lossless vector quantization algorithm for compression of remotely sensed images

Research output: Contribution to journalConference article

Abstract

Most compression algorithms are desired for minimizing a squared error criterion. The squared error criterion does not accurately represent the fidelity requirements for scientific image compression. In this paper we propose a distortion measure which correlates with subjective evaluations, and an adaptive vector quantization algorithm which minimizes this distortion measure. A new approach to codebook design is presented to replace the nearest neighbor approach.
