首先对两幅需要进行融合的图像完成小波变换,小波系数位于LL,LH,HL以及HH这4个频带。小波系数的绝对值越大,其对应于更为尖锐的灰度变化(即图像中的突出特征部分),在小波融合中,一个主要的思想便是判断两幅原始图像对应小波系数的绝对值大小。在变换域的每一个小波系数都取绝对值相对大的那一个,这样,便实现了在所有分辨率级别上的小波系数融合,并且新的小波系数完好地保存了更多的频带特征。所有融合后的图像可以通过对新的小波系数进行小波逆变换得到。-First two images need to comp

图象增强小波变换将一幅图象分解为大小、位置与方向都不同的分量。在做逆变换之前能改变小波变换域中某些系数的大小,,这样就能够洋选择的放大所感兴趣的分量而减小不需要的分量。给定一个图象信号,用二维小波分析析对图象进行增强处理。
