In this paper

First papers about multistage vector quantization (MSVQ) and Simulated annealing (SA) technique were consulted

based on a multistage vector quantization and Simulated annealing technique

we researched optimal codebook conditions of VQ

and present the algorithm of multistage vector quantization based on simulated annealing(SA-MSVQ). The scheme give full play to MSVQ and SA' s merits for image coding

counteract own weakness of multistage vector quantization based on simulated annealing. Theory and experimental results show that not only computation and storage is significantly lower

but also obtained a good image resume under the high compress ratio.
