denoising

此程序实现图象傅立叶变换、离散傅立叶变换和小波变换、可以自己设定小波变换的参数(this procedure image Fourier transform, discrete Fourier transform and wavelet transform, can set their own parameters of wavelet transform)

图像处理中，有关二维离散小波变换的PPT例程，富有参考价值。(Image processing related to the two-dimensional discrete wavelet transform PPT routines, full of reference value.)

分别用小波、分形的方法对图像进行去噪，并对这两种方法的结果进行了比较。(Wavelet, respectively, the method of fractal image denoising, and the results of these two methods are compared.)

This is a MATLAB code used to calculate the PSNR of a function.
