该matlab源代码能对地震数据进行克希霍夫偏移。(The program kirchhoff offset seismic data)

抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定.(parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

ML decoder for QPSK signal to find symbol error rate.

按照KC Ho 的一篇论文Source Localization Using TDOA and FDOA Measurements in the Presence of Receiver Location Errors_ Analysis and Solution写的仿真代码，用于3基站以上对固定目标进行定位，方法是两步最小二乘，实际上第二步完全不能用，不知道是不是自己写的有问题，欢迎讨论~(According to the paper "Source Localization Using TDOA and FDOA Measurements in the Presence of Receiver Location Errors_ Analysis and Solution" written by KC Ho, I write the code for simulation, the method is the least square, in fact, the second step is completely out of use, I do not know whether it is my problem or not, if you have any idea, welcome to discuss)

该代码主要实现的是基于PCA（主成分分析）的人脸识别程序，其中包含有人脸图像预处理、训练部分和测试部分这三大模块。测试用的照片是标准数据中的人脸图像，均为外国人脸。

YUV与RGB颜色空间之间的转换，转换效果很好的。(YUV and RGB color space conversion between the effect of a very good conversion.)

说明：  matlab实现DTMF辩音程序，要求由用户生成DTMF音保存为wav格式，即可。(DTMF tone debate matlab implementation procedures required DTMF tone generated by the user is saved as wav format, you can.)

说明：  先对图像均衡化 增强对比度 加噪声 然后分别进行空域和频域滤波(First, the contrast enhanced image equalization plus noise and then separate airspace and frequency domain filtering)
