基于焊接图片的pca降维，knn分类算法。(Pca-based solder image dimension reduction, knn classification algorithm.)

说明：  这是一个伽玛图像校正程序，首先读入原始图像，然后利用事先在matlab中计算得到的对每个灰度值校正后的数值替代原灰度值即可。(this is a gama image revising program. it uses revised grey level obtained from matlab to substitute original image data to fulfill this task.)

哈尔滨工程大学研究生随机过程实验作业，里面有作业matlab源程序(Harbin Engineering University Graduate random process lab assignments, which has an operating matlab source)

该代码是采用Mean-shift算法进行目标跟踪，该代码可以正常运行，且简单易懂。(The code is the use of Mean-shift algorithm to track the target, the code can run normally, and it is easy to understand. )

说明：  脑电信号功率谱，用于计算各个通道的功率谱，功率谱密度(The power spectrum of eeg signal is used to calculate the power spectrum and power spectrum density of each channel)

matlab与VC混合编程，输入方程，与自变量范围，就可以计算方程的值，与倒竖值。(mixed programming with VC matlab input equation, and the scope of the independent variables, we can calculate the value equation, and the inverted vertical value.)
