fast fourier transform (FFT) code in MatLab

一个牛人写的99行的优化程序的文章 A 99 LINE TOPOLOGY OPTIMIZATION CODE BY OLE SIGMUND(a cattle written by the 99 articles optimization program LINE A 99 TOPOLOGY OPTI MIZATION CODE BY OLE SIGMUND)

说明：  This code is used for trajectory tracking using PF.

This code applies global histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The output is definitely a better contrast image as compared to the input

里面包含五个有关matlab的学习的资料，特别适合初学者使用。(a very good learning material of matlab learning.)

利用fft2对图像傅里叶变换，在用lpfilter生成高斯低通滤波器，进行过滤再进行反变换最后显示(Use fft2 the image Fourier transform, in with lpfilter generate Gaussian low-pass filter for filtering the inverse transform last displayed)

说明：  该课题为基于MATLAB的数字水印系统。包括离散余弦DCT和小波变换DWT两种算法的对比，有一个GUI界面，包括嵌入，加噪，旋转，剪切，压缩等多种攻击，提取候，具有评价指标PSNR,NC等来评价算法的鲁棒性(This project is a digital watermarking system based on MATLAB. It includes the comparison of DCT and DWT. It has a GUI interface, including embedding, noise adding, rotation, cutting, compression and other attacks, extraction, and evaluation index PSNR, NC to evaluate the robustness of the algorithm)
