GAC evolves the level set function according to geodesic active contour model(GAC evolves the level set function accordi Vi to geodesic active contour model)

fast RPCA背景检测,较为经典的一种算法，亲测可用(fast rpca method for background selection)

利用matlab实现图像的边界检测。包括sobels算子，prewitt算子，还包括图像的边界追踪(use matlab to detect the boundary of the image)

Image to be embedded into an image

利用径向基函数的方法进行隐式表面重建，matlab代码(Radial basis function method for implicit surface reconstruction)

图像的相关系数是衡量两幅图像的相关程度的，本代码直接通过选定区域计算出相关系数！(image correlation coefficient is a measure of two images of the code directly through selected regional correlation coefficient calculated!)

以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

此为canny算子的 matlab源代码(This is a canny operator matlab source code)
