Curves Evolving Based on Level Set Method
基于Level Set方法的曲线演化

Level Set method is a power tool for tracking the evolution of fronts propagating with curvature dependent speed. Since its introduction, Level Set method has been used in a wide collection of problems such as medical image processing, the simulation of natural phenomenon and computer vision. In practical applications, two of the most important algorithms are how to smooth the grid value and track the fronts contour after some time steps. In this paper, a simple method is introduced to smooth the value of Level Set function.It uses only intra-interpolation to clear out all of the single points and soms of the ambiguous points.Use the contor line tracking method introduced in this paper,people can get the contour lies of all of the curves in a plane,even if there exists some redundant points.The experimental results show that this method is simple and useful,and can be used to wide fields concerning with fronts propagating.
