中值滤波窗口大小影响滤波器性能,3×3滤波窗口可以很好地保持图像细节。提出一种新的自适应中值滤波方法。将3×3窗口中心的极值点作为候选噪声点,若候选噪声点仍然是7×7窗口的极值点,则该点即是噪声点。若以噪声点为中心的3×3滤波窗口的中值不是噪声,则噪声用中值替换。重复以上过程,直到没有噪声点被替换。(Median filter window size affect the filter performance, 33 filter window can be well preserving image detail. Propose a new adaptive median filtering method. The 33 extreme point of the center of the window as the candidate noise the candidate noise is still 77 extreme points of the window, the point is that the noise point. Terms of noise centered on the point 33 filtering window value is not a noise, the noise is replaced with the median. The process is repeated until there is no noise point is replaced.)

说明：  雷达数据处理程序，对于虚假目标的产生，采用在距离、方位角、俯仰角三个方面分别产生随机噪声。(There are six tracks in the main function, which are straight track 1, circular track, straight track 2, straight track 3, figure 8 Track and ellipse track. The generation method is to first generate the track in rectangular coordinate system according to the motion equations of various tracks, in which 8-word track and ellipse track are generated by calling the functions of eighttrack and ellipsetrack respectively, and then use the coordinate system transformation to convert the value of rectangular coordinate system into the value of polar coordinate system, that is, distance, azimuth and pitch angle. It is worth noting that the image should be considered in the transformation process)

说明：  基于matlab的图像的检测与识别，车牌识别系统(Matlab image based on the detection and recognition, license plate recognition system)

说明：  有多个文件 可以根据文件名和注释进行选择 提取算法可以根据嵌入算法 自行写出 提供了较好的抗压缩和抗剪切的效果(a number of documents under the file name and choose Notes extraction algorithm can write their own algorithms embedded mention for a better compression and anti-shear effect)

说明：  功能:在彩色图片上令肤色区域为白色,其余为黑色,并用矩形将各连通区域标志出来,用matlab实现(Function: to make color in the color picture on the white area, the rest is black, and will each connected region with a rectangular logo out to achieve with matlab)

Matlab 应用，基于最近相邻节点的旅行商问题解决模式(Nearest Neighbor algorithm ，for the Travelling Salesman Problem)

denoise the bayez noise of image wavelet

说明：  二维无网格EFG计算程序，由MLS方法生成新函数(Two-dimensional meshless EFG computer program to generate a new function by the MLS method)

最小二乘法是一种数学优化技术。它通过最小化误差的平方和寻找数据的最佳函数匹配。利用最小二乘法可以简便地求得未知的数据，并使得这些求得的数据与实际数据之间误差的平方和为最小。最小二乘法还可用于曲线拟合。其他一些优化问题也可通过最小化能量或最大化熵用最小二乘法来表达。(Least squares method is a mathematical optimization techniques. It matches by squaring and finding data to minimize the error of the best functions. Least square method can easily be obtained unknown data, and so these squared error between the obtained data and the actual data and the minimum. The least squares method can be used for curve fitting. Some other optimization problems can be expressed by the least squares method by minimizing or maximizing entropy energy.)
