Iterative Gradient Vector Flow Snake for Segmentation of Image
Pan Zhen-kuan · Journal of Qingdao University · 2005
Gradient Vector Flow Snake is one of the most effective tools for 2D/3D image segmentation. But GVF Snake can't move into boundary concavities when the concavities are long and thin. The Iterative GVF Snake is proposed to resolve this problem. The method is iterating GVF Snake by adjusting the result of convergence of current GVF Snake as the initial contour of next GVF Snake. Experiments show that the Iterative GVF Snake performs well for segmentation of images that have thin and long concavities.
