An Image Coding Scheme for Multistage Vector Quantization Based on Simulated Annealing
|
Abstract:
In this paper, First papers about multistage vector quantizat ion (MSVQ) and Simulated annealing (SA) technique were consulted, based on a mul tistage vector quantization and Simulated annealing technique, we researched op timal codebook conditions of VQ, and present the algorithm of multistage vector quantization based on simulated annealing(SA-MSVQ). The scheme give full play t o MSVQ and SA's merits for image coding, counteract own weakness of multistage v ector quantization based on simulated annealing. Theory and experimental results show that not only computation and storage is significantly lower, but also obt ained a good image resume under the high compress ratio.
