1 Contour evolution scheme for variational image segmentation and smoothing S. Mahmoodi and B.S. Sharif

2 Outline Introduction Modifications And Implementation Result

3 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

4 Contour length minimization term is dropped Gaussian filter is applied to φ(x,y) in every iteration to improve the performance of the algorithm in very noisy images C-V models proposed are extended to piecewise polynamials and Fourier series

5 f(x,y) is the smoothed continuous function g(x,y) is the piecewise continuous function With the Neumann boundary condition
