预扫描算法求解图像分割的Chan-Vese模型

本文提出了一种新的有效的算法来求解图像分割中的Chan-Vese模型。新算法避免了求解PDE的过程,极大地提高了图像分割的运算速度。这种算法保持了C-V模型和水平集方法的优点,能够自动处理图像分割过程中边缘的拓扑变形,保持边缘的尖角以及对于非凸边缘的有效的检测等等。这种算法思路简单,很容易推广到任意有限维的图像分割问题的求解中。

Pre-sweeping Algorithm for Solving the Chan-Vese Model in Image Segmentation

This paper is concerned with a novel and effcient algorithm,the pre-sweeping algorithm,for solving the Chan-Vese model in image segmentation.This algorithm avoids solving the Euler-Lagrange equation corresponding to the energy function.It improves the com-putational speed dramatically when applied to the Chan-Vese image segmentation model and keeps all the advantages of the level set method such as automatically handling the topological variety,preserving the sharp-angle of the curve,etc.Our algorithm is al...
