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。
After the image wavelet transform [1], the characteristics of each sub-image data are discussed. Based on these characteristics, a method of block segmentation and a method of vector quantization coding are proposed. The data smoothness and ergodicity Data detection methods; and then study the wavelet transform in thermal image compression applications.
