将一副彩色图像转为灰度图像，截取部分，并找到质心位置(Centroid calculation of gray image)

IEC61804-2国际标准，过程控制的功能模块(IEC61804-2 international standard, process control function modules)

This code perform the DCT and quantization on all the channels without any sub-sampling and for the compression of color images, they are first converted to the YCbCr color format and vice versa, use the function rgb2ycbcr and ycbcr2rgb.

ofdm系统的简单仿真，基于matlab环境，可以借此更好的理解ofdm传输原理(simple simulation ofdm systems, based on the matlab environment, can take a better understanding of the principle of ofdm transmission)

说明：  在模式识别应用中，用分支定界法(branch-and-board method)进行特征的选择。该程序在matlab环境下实现了该算法，以从六个特征中选择两个最佳特征为例(In pattern recognition applications, using branch and bound method (branch-and-board method) to carry out the characteristics of choice. The program in the matlab environment to achieve the algorithm to select from the following six characteristics of the best features of the two as an example)
