USEING IMPROVED SNAKE MODEL TO DETECT CONTOUR OF BLOOD VESSEL

Luo Peng Lu Zongqi Gao Dunyue (Institute of Automation,East China University of Science and Technology,Shanghai 200237)  
In this paper,an improved active contour model with centripetal force is presented.We proposed an auto-initialization algorithm to locate the initial control point at first.Then to locate the final snake using improved active contour model with centripetal force.The method is applied to blood vessel image to detect its contour.Experiments show it is effective to detect concave contour and multiple object in an image.
