一个matlab实现的image matting的代码。包括Possion matting等四种不同的matting算法的实现。(Achieved a matlab code image matting. Possion matting, such as including four different types of matting algorithm.)

对高光谱图像进行目标检测，首先滤波处理然后降维，利用输出能量最小原则用于探测亚像元的小目标。(In target detection of hyperspectral images, first filter processing and then dimensionality reduction are used to detect sub-pixel small targets by using the principle of minimum output energy.)

制作二维地形,并且可以对其添加线表示，还可以做分层设色二维地形图图(Dimensional terrain)

用于求取三维点云数据的法向量，我的人脸建模就是用的这个，效果很好，但必须保证点云没有重叠的，否则会出现严重错误。(Strike a 3D point cloud data for normal vectors, and my face is to use this model, the effect is very good, but must ensure that there is no overlap of the point cloud, there would be a serious mistake.)

自己编写的散斑生成算法，对于三维重建有很大的帮助(the generation algorithm of the speckle image， which is helpful for the three dimensional reconstruction)
