摘要
卫星图像是一个种高熵值图像,本文针对卫星图像研究了格矢量量化编码压缩方法,分析了格矢量量化特性,并列举了几种格。实验结果表明,格矢量量化编码压缩方法失真小,计算量少,比较适用于卫星图像编码压缩。
Satellite image is a kind of high entropy images. In this paper, a method of the lattice vector quantization (LVQ) for coding and compression is studied for satellite image. The property of lattice vector quantization is analyzed. Some kinds of lattice are listed. The experiment result indicates that the distortion is little by using the LVQ method for coding and compression, and the computational expense is low. This method is more suitable for coding and compression of satellite image.
