This Matlab code implements an edge based geometric active contour model without reinitialization. MATLAB Release: R13SP1 This Matlab code implements the level set method in Chunming Li et al s paper \"Level Set Evolution without Re-initia

利用水平集函数来检测物体轮廓，一般水平集收敛用到signed distance function的，但是这里实现的程序不用每次都要进行reinitialization就可以使水平集函数趋于收敛。-The use of level set function to detect an object contour, the general level set signed distance function used in the convergence, but the program here

by traditional level set based segmentation models. In this paper, we propose a new level set method integrating local and global intensity information adaptively to segment inhomogeneous images. The local image information is associated with the
