本程序采用半隐式方案实现变分水平集图像分割方法中的模型(Active contour ithout edge)-This program uses the program to achieve semi-implicit variational level set image segmentation methods model (Active contour ithout edge)

我们使用了一种变分公式来纠正水平集函数与符号距离函数的偏差,从而实现了水平集函数在演化过程中不需要再次初始化的目标。-we use a variational formulation that forces the level set function to be close to a signed distance function, so realize the level set function without re-initialization during the evolution
