摘要
对图像进行小波变换［１］后各子图像数据的特性进行了探讨，并利用这些特性提出了一种方块分割方法和一种矢量量化编码时所需的数据平稳性和各态遍历性的大数据检测方法；然后研究了小波变换在热图像压缩中的应用。
This paper first of all based on the wavelet pyramidel decomposition of the images,the distributed properties in the data of each subband are analyzed in detail.According to these properties,a modified block partition method and a large number determined method used in vector quantization are presented.Then the thermal image compression using wavelet transformation has been studied.
