说明：  基于matlab的简单手势识别代码，初学者可自行下载。(Simple gesture recognition code, beginners can download.)

说明：  代码很好的实现了基于a-star的最短路径寻找算法，并可以对寻找的路径有一个限制(Code is a good realization of a-star-based shortest path search algorithms, and can find the path there is a limit)

可以用于图像分割的KNN分类器，简单好用！(knn classification)

对整幅三维影像数据进行Butterworth高通滤波处理（10阶2次），先进行傅里叶变换，利用巴特沃斯高通滤波器数学模型进行变换，在傅里叶逆变换得到新数据(For the entire three-dimensional image data Butterworth high-pass filtering (10-order twice), the first Fourier transform, use Butterworth high-pass filter to transform the mathematical model, the inverse Fourier transform to obtain new data)

说明：   最简单的差分格式有向前、向后和中心3种。 向前差分：f (n)=f(n+1)-f(n) 向后差分：f (n)=f(n)-f(n-1) 中心差分：f (n)=[f(n+1)-f(n-1)]/2(The easiest difference format forward, backward, and three kinds of centers. Forward differencing: f (n) = f (n+ 1)-f (n) Backward difference: f (n) = f (n)-f (n-1) Central difference: f (n) = [f (n+ 1)-f (n-1)]/2)

应用Matlab写的HDR图像处理完整工具，包括：合成HDR图像、TMO等，路径完整，亦包括示例、例图。非常有用的学习工具。(It s a totally codes of HDR image processing, including HDRI generation, TMO, etc. Very useful tool for study.)

图像重构实现干涉条纹缺陷图的缺陷检测，能很好的滤除条纹，得到缺陷(Interference fringe image reconstruction to achieve defect detection defect map can be a very good filter stripes)

pcl 3d 文件格式转换，点云读取与显示(PCL 3D file format conversion, point cloud reading and display)

二维最大熵阈值分割法，较一维有很好的去噪效果(Two-dimensional maximum entropy threshold segmentation method, the more one-dimensional results have a good de-noising)

几何变换，包括图形的基本变化，以及计算机图形学中的算法(Geometric transformations, including changes in the basic graphics, and computer graphics algorithms)
