一个一个重构算法--子空间追踪方法集合程序

显示原图，matlab.良好的操作性良好的操作性(Show the image, matlab. Good good interoperability interoperability)

the upsample and down sample function rebuild as new code resamplex

Feature extraction for clasification

计算两幅图像的峰值信噪比。图像是表示地个像素点所用的二进制位数，即位深。计算PSNR(Calculate PSNR of two images. Image pixel is expressed in a number of bits used, ascended the throne deep. Calculation of PSNR)

说明：  mppt with mrac system

用matlab画几个六边形。。。。。。。。。。。。。(Draw a few hexagons with MATLAB)

预备实验 Matlab软件环境的熟悉，里面一些最简单的只是知识，可以帮助刚入门的学习(Prepared to experiment with Matlab software environment, which is just some of the most simple knowledge that can help just getting started learning)

说明：  利用小波分析的方法，来实现数字图像的分解(using wavelet for image)

Wave Spectrum Radial Plot

多尺度分解图像，利用小波的模极大值获取图像的边缘特征，并绘图(Multi-scale decomposition of the image, the wavelet modulus maximum to obtain the image edge features, and drawing)
