Codes

Calculate the Mean Square Error (MSE) and the Peak Signal to Noise Ratio (PSNR) for different JPEG compression ratios.

MATLAB高斯消去法解方程组，我调试过了，可以用的。欢迎大家下载使用！(MATLAB Gaussian elimination solution of equations, I have debug off, and can be used. Welcome to download!)

说明：  目标匹配经典特征shape context的Matlab源码！(The source code of the shape context!)

说明：  图像压缩，主成分分析的应用介绍，很有用啊(Image compression, principal component analysis applications introduced useful)

说明：  FBCCA是处理SSVEP信号重要分类识别算法(Fbcca is an important classification and recognition algorithm for processing SSVEP signals)

hotelling transformation has been written with help of Matlab 2007a. This technology has been applied to transform images. A test image has been included in the file for explanation. It accpets 256 color map bmp image as input and produces the output.

识别眼部，均值滤波，二值化后，分割出眼部(Identification of the eye, mean filtering, thresholding, the segmented eye)

in this image thresholding is done.image thresholding is getting by using seed polints concept

说明：  在MATLAB环境中，利用简单的加法和乘法实现基2时间抽取的FFT变换，并且能够计算出峰值点的最大值,数据点数为2的整数次幂。学习程序有利于对FFT变换的理解，以及在单片机环境或者是DSP环境中编写FFT变换C语言程序。(In the MATLAB environment, using simple addition and multiplication of time taken to achieve the base 2 FFT transform, and can calculate the maximum peak point. Learning process is conducive to the understanding of the FFT transform, and the DSP in the microcontroller environment, the environment or the preparation of FFT, C language program.)
