MATLAB实现图像的DCT变换及选择性重构(MATLAB for image reconstruction of DCT transform )

使用蚁群算法并进行改进，利用改进的蚁群算法优化BP神经网络的程序(Ant colony algorithm and improved use of improved ant colony algorithm to optimize BP neural network program)

仿MATLAB矩阵C++运算库,包括加、减、乘、除、点加、点减、点乘、点除、赋值、转置、rank、det、eig、svd、pinv、power等的运算。inv运算使用pinv运算。最难实现的是非方阵的除法。(MatLab Matrix simulator)

标准的遗传算法优化最小二乘支持向量机，能很好的实现参数寻优功能(Standard genetic algorithm optimization least squares support vector machines, can achieve good functional parameter optimization)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

命令解析函数getopt_long()接口的使用(Order analytic function getopt_long () interface to use)

这个是一个好好用的完美挂请大家用用好不好用大家说说(PostScript(R) Printer Description (a.k.a. PPD) files are text files containing information about special features available on PostScript printers such as paper sizes, screen values and fonts available on your printer. These files are in a very specific format that can be read by software applications. The information is used when printing your document by the printer driver for decision making purposes or to invoke particular features of the printer. )

这是CS-mRI代码,主要应用于医学磁共振图片的压缩感知处理代码(This is the CS-mRI code, mainly used in medical magnetic resonance image compression perceptual processing code)

matlab 的回归分析的源码，包含课件，相当的不错。(matlab source code of the regression analysis, including the courseware, very good.)

Matlab入门,非常好的资料,对于初学者尽快熟悉运用是个不错的帮手(Matlab entry, very good information for beginners as familiar with the use is a good helper)
