Outline

Introduction Modifications And Implementation Result

Introduction

Use M-S function without the contour length minimization term

Based on the C-V model Three modification to the M-S and C-V

models are proposed

Contour length minimization term is dropped Gaussian filter is applied to φ(x,y) in every itera

tion to improve the performance of the algorithm in very noisy images

C-V models proposed are extended to piecewise polynamials and Fourier series

f(x,y) is the smoothed continuous function

g(x,y) is the piecewise continuous function

With the Neumann boundary condition

Modifications and implementation
