This code is improving parts of the image with imcrop according to the 2-D histogram (mesh).

matlab互交式进行数据统计分析的工具包。利用gui界面给方便进行基本的数据统计分析(Matlab interactive statistical data analysis tool kits. Use gui interface to facilitate basic statistical analysis of data)

its matlab for recognition

matlab编写的视频关键帧提取程序，可自动从视频中提取帧，提取第几帧可在程序中自行设定，另附有批量处理视频的主函数。(matlab prepared video key frame extraction procedures can be automatically extracted from video frames to extract the first few frames can be set in the program, batch processing video attached with the main function.)

说明：  主要是通过GA和PSO的全局搜索能力，用于改进BP网络的权值阈值(It is mainly used to improve the weight threshold of BP network)

维纳滤波进行语音信号的增强，是学习现代信号处理和语音增强的很好的学习程序。(Wiener filtering speech enhancement is a good learning process for learning modern signal processing and speech enhancement.)

这是一个用Matlab编写的用于WSN中质心算法计算节点位置的源程序(this resource is used to calculate the locationof the nodes in WSN)

通过计算垂直缆地震产生各种波的时距曲线公式，画出其波形(By calculating Time-distance curve equation of various waveforms produced by vertical earthquakes，and draw them with matlab )

也是利用最小二乘法对椭圆进行数据拟合，不过考虑到图像大小问题，这里只选取100个边缘点，点的个数也可以自行设置。(Ellipse is the least square method of data fitting, but taking into account the size of the image, here select only edge points 100, the number of points you can set your own.)
