New Implementation

A new implementation can be found in USTC_DIA-Levelset_method.

Level Set Evolution Without Re-initialization Implementation

新的代码包括三项:

  1. new_demo.m 算法的参数,level-set function 初始化,外层迭代
  2. new_revolution.m 内层循环,依据推导出的算法实现level-set function 的迭代
  3. edge_detector.m 实现 $$ g=\frac{1}{1+|{\bigtriangledown G_{\sigma}}*I|^{2}}$$

结果

​ 对于three.bmp和twocell.bmp分割效果较好,对vessel.bmp分割效果较差

​ 初始值zero level set函数的包含的区域要包含目标(nu为正值)

公式的推导如下:
