利用fortran编写的实现二维fft的程序
- 该程序能够有效计算点数为2的N次方情况下的二维fft变换,已经经过matlab的验证,只要稍微改动一下,就可以计算二维ifft变换,当然,也可以按照程序中的方法,计算更维的fft。程序中fai0r数组为初始点(也就是要计算的点)的实部,fai0i数组为初始点的虚部。

二维小波变换
- 关于二维小波变换的程序 [精华] 说明:此算法重在概念,速度并不是很快。因为FOR循环的缘故。此程序从循环矩阵的观点出发,把圆周卷积和快速幅里叶变换建立了联系。实现了分解和无失真重构。它只做了一层分解,即将256x256图形分解成为64x64的四个图形,避免了使用WKEEP()的困惑。主要思想为用小波滤波器族构造正交阵W,变换写为B=W*A*W ,反变换为:A=W *A*W,这与所有正交变换无异。W为循环正交矩阵,因此可用F
