二维傅里叶变换,对图像进行二维傅里叶变换处理(Two-Dimensional Fast Fourier Transform The purpose of this project is to develop a 2-D FFT program "package" that will be used in several other projects that follow. Your implementation must have the capabilities to: (a) Multiply the input image by (-1)x+y to center the transform for filtering. (b) Multiply the resulting (complex) array by a real function (in the sense that the the real coefficients multiply both the real and imaginary parts of the transforms). Recall that multiplication of two images is done on pairs of corresponding elements. (c) Compute the inverse Fourier transform. (d) Multiply the result by (-1)x+y and take the real part. (e) Compute the spectrum.)

说明：  用于近红外光谱建模前，进行光谱预处理，一般与snv有类似作用(Model for near infrared spectroscopy before, spectral preprocessing, generally have a similar effect with snv)

说明：  pso生物优化算法应用的实例源代码，根据自己需要可以更改里面的fitness具体情况自己更改 (pso examples of biological optimization application source code, according to their fitness needs to change the situation inside their own change)

BM3D的程序，基于最小均方误差准则。很好用(Date released 1/08/2012, version 0.1. Functions for Matlab for the denoising of a SAR image corrupted by multiplicative speckle noise with the technique described in A Nonlocal SAR Image Denoising Algorithm Based on LLMMSE Wavelet Shrinkage )
