GS算法，高斯光束整形成矩形光斑，或者根据自制的图片进行逆推相位(GS algorithm, Gaussian beam shaping)

应用于fluent的UDF程序，用于修正液滴表面轮廓(The UDF is applied fluent procedures for correcting the droplet surface contour)

基于麦克风阵列的高信噪比定向采音系统_何强(Based on high SNR directional microphone arrays adopt sound system _ He Qiang)

图像分割的一个小程序。经过检验，直接运行没问题。希望对大家有用，在这里分享了。(A small program for image segmentation. Tested directly run no problem. We want to share here.)

C标准函数源码，十分丰富，便于移植和裁剪。(C standard function source code, is very rich, easy to transplant and tailoring.)

将两张图像进行图像相减或相处，使两张图片叠加。(The two images are subtracted or coexisted, so that the two images are superimposed.)

基于不精确拉格郞日算子法的低秩矩阵重构程序，可以用于图像分割，将目标图像分割为背景和前景，从而将前景分离出来。(Lagrangian method based on imprecise low rank matrix reconstruction procedures can be used for image segmentation, the target image into background and foreground, which will separate the foreground.)

给予matlab的图像分割例程，内附相关图片及程序。(Image segmentation routine MATLAB, containing the relevant pictures and program. )

说明：  几种图像融合评价指标，AG,EN,FMI,MI,Qab,Qw,SF,SSIM，即平均梯度AG、信息熵EN、特征互信息FMI、互信息MI、边缘信息保持量Qab、加权融合质量评价因子Qw、空间频率SF和相似性指数SSIM。能较好的描述图像融合结果，稳定性较好。(Several evaluation indexes of image fusion, Ag, en, FMI, MI, qAB, QW, SF, SSIM, namely average gradient AG, information entropy En, feature mutual information FMI, mutual information MI, edge information retention qAB, weighted fusion quality evaluation factor QW, spatial frequency SF and similarity index SSIM. It can describe the result of image fusion well and has good stability.)

说明：  裁剪图像为固定大小，非常简单，只需要设定图像裁剪起始位置以及图像裁剪大小即可，非常方便。(It is very simple to crop the image to a fixed size. It is very convenient to set the starting position and size of the image clipping)
