Image Fusion is the process of combining information of two or more images into a single image which can retain all important features of the all original images. Input to fusion is a set of images taken from different modalities of the same scene. O

针对传统小波变换过程复杂的缺点和SPIHT 算法编码过程重复运算、存储量大的问题。首先分析了小波基 和小波分解层数的选取, 然后提出了一种改进的SPIH T 算法, 该算法利用可变阈值对SPIH T 算法中初始子带进行分类得 到一种更有效的编码算法。-Against disadvantages of traditional process of complex wavelet transform and SPIHT algorithm coding process repeated op
