小波变换等多分辨分析方法能够处理图像配准中图像的全局和局部变形 .小波变换在配准的同时还可以进行图像压缩 .作为新近发展起来的多分辨分析方法 ,复数小波变换提供了移动不变性和方向选择性滤波器 .在压缩比为 4 0∶1时 ,复数小波变换所实现的天蓝色链霉菌蛋白组凝胶图像压缩结果与离散小波变换结果十分接近 .
Wavelet transform and other multiresolution analysis methods can handle global and local image warping in image registration.Wavelet transform can be used for image compression simultaneously with registration.As a newly developed multiresolution analysis method, Denaturing and direction-selective filters.When the compression ratio is 40: 1, the result of compressing Streptomyces coerioides gel images by complex wavelet transform is very close to that of discrete wavelet transform.
