用计算机进行数字图像处理，使用matlab环境，对图像进行增强，平滑与锐化，分割，变换，压缩与编码，是平常实验的好选择。(Using computer digital image processing, the use of matlab environment, enhance the image, smoothing and sharpening, segmentation, transform, compression and encoding, is usually a good choice experiment.)

it is a transform for copmpressing and decompressing and removing noise effectively.

This code measures the perimeter of the land.

Vectorial control, MAX STEP SIZE : 0.00001

说明：  Matlab toolbox for parsing optimal control problems into nonlinear programming problem. Please read the documentation under subdirectory manual. There are a few examples that should help you get started.

MUSIC方法估计信号方位(MUSIC methods are used to estimate the signal direction)

灰色关联分析中，计算关联度系数，以寻找出两个变量间的关联程度(This program will caculate the calculation of correlation coefficients in order to find out the correlation between two variables in the Grey relational analysis)

实现无边界主动轮廓，能够直接运行的，很好用。希望对大家有用(active contour without edges)

powel optimization method

是我见过讲的最详细的关于稀疏信号的书，讲解了稀疏分解，以及书后的程序都是很好用的(Ive seen talking about the most detailed book about the sparse signal, explained the sparse decomposition, and program books are well used after)
