matlab开发环境，．编程实现二维DFT的变换，并与标准函数结果fft2进行比较，基本傅里叶、离散余弦变换，空域（完成两个程序） 增强噪声后再进行处理，利用标准函数，求图像阈值分割、边缘检测的基本使用（lena256.bmp，方法：graythresh、edge），求分水岭，利用标准函数dwt2、idwt2分解图像man_pic.jpg，基本 BP-BPbase1 (matlab development environment. Programming dimensional DFT transform, and with the standard functions compare results fft2 basic Fourier, discrete cosine transform, airspace (to complete the two programs) to enhance the noise and then processed using standard functions for image thresholding, edge Detection of basic use (lena256.bmp, method: graythresh, edge), seeking watershed, using a standard function dwt2, idwt2 decomposed image man_pic.jpg, basic BP-BPbase1)

这是一个很基本的pso算法的matlab的源码。比较的简单，但是可以再这个基础上修改的(This is a very basic PSO algorithm matlab source code. Comparison of the simple, but can be modified based on this)

说明：  利用matlab实现基于小波的图像增强以及去噪，效果很好(Using matlab wavelet-based image enhancement and denoising, the effect is very good)

This toolbox has functions to perform nonlinear diffusion images. This kind of image filtering is particularly useful for reducing noise and to simplify images for further segmentation. Much of these functions are based on Perona and Malick s work, and also on J. Weickert s papers. The fast AOS diffusion is implemented. There is also 3D diffusion functions, color image diffusion and Coherence-Enhancing diffusion (This toolbox has functions to perform nonl inear diffusion images. This kind of image fi ltering is particularly useful for reducing no ise and to simplify images for further segmenta tion.

There is also 3D diffusi on functions, color image diffusion and Coherence- enhancin g diffusion)

用JACOBI迭代法求解线性代数方程组，此迭代法是数值计算基本方法之一。(Use JACOBI iterative method for solving linear algebraic equations, and this iteration method is one of the basic method of numerical calculation.)

This m file reads the V1 files of strong motion, i.e. the raw format as recorded by the accelerographs. Then seperates the three components, and puts the earthquake and station specifications into branches of a structure variable.

基于LSB的数字水印算法，MATLAB，简单易懂，嵌入与提取(Digital watermarking algorithm based on LSB, MATLAB)

MATLAB常用函数参考,查找起来非常方便，是matlab必备工具书(MATLAB function reference commonly used, search is very convenient, is an indispensable tool for matlab book)
