1、《小波图像分解与重构程序存在的问题与解决办法》 我编写程序时尽量实现模块化，方便不同功能程序之间的调用。以上程序实现了一维、二维小波分解与重构的功能，接下来我们就可以此为基础，探讨小波信号压缩和图像融合等技术了。(1, " Wavelet image decomposition and reconstruction process problems and solutions" when I try to modular programming, to facilitate calls between different functional processes. Program achieved more than one-dimensional, two-dimensional Wavelet function, then we can take this as the basis of wavelet signal compression and image fusion with the.)
