说明：  利用matlab平台产生周期方波信号和扫频信号，可改变周期和幅值(Matlab produce cycle of square wave signals)

四邻域加权平均算法 实现了图像的高质量重采样(resample function)

Voronoi图是以两点间线段的长度作为距离 ,对平面的一种分割。然而 ,在地理环境中 ,存在着许多自然的或人为的障碍 ,使得从一点到另一点不能直线到达。为了扩大Voronoi图的应用领域 ,本文对传统的Voronoi图进行扩充 ,给出了障碍Voronoi图的定义、性质 ,以及离散生成线段障碍Voronoi图的方法(Voronoi diagram based on the length of line between two points as the distance from a partition of the plane. However, in the geographical environment, there are many natural or man-made obstacles, making from one point to another point of arrival can not be a straight line. In order to expand the area of Voronoi diagram, Voronoi In this paper, the traditional expansion plans, given the obstacles to the definition of Voronoi diagram, the nature of the discrete Voronoi diagram generation segment of the barrier method)

FLAc3D数值模拟软件命令流，煤层工作面开挖模拟(FLAc3D numerical simulation software command stream, seam face excavation simulation)

meanshift图像跟踪算法，实现目标物体的连续跟踪(meanshift image tracking algorithm to achieve continuous tracking of the target object)

脆弱水印提取算法，与embed.rar中的嵌入算法相对应，可以提供较好的篡改定位(Fragile watermark extraction algorithm, and embed.rar correspond to the embedding algorithm can provide better tamper positioning)

计算关联成像 或者说鬼成像的图像求解算法，用来计算得出bmp图像(Associated with imaging or ghost imaging algorithm computing image for calculated bmp image)

说明：  这个程序是用harr小波对图像进行分解和重构，是个可执行的源代码，已通过调试，大家可用来学习(this procedure is right Harr wavelet image decomposition and reconstruction, is the source of executable code, the debugging, you can be used for learning)

对图像进行欠采样，然后利用OMP 进行重构，其中用到了小波矩阵进行稀疏(The image is undersampled and then reconstructed by OMP, in which the wavelet matrix is used for sparsity.)

说明：  给出一些离散的点，根据最小二乘法求出拟合的直线。(If there are some discrete points, you can get a line based on least square method.)
