【Abstract】 In this paper,the Chan-vese(CV) method and its geometry character are discussed in detail.The signed distance function is analyzed in the process of level set evolution,and the CV method is revised by introducing a new energy which can reconcile the signed distance function.Finally experimental results show that the revised method is effective to speed up the traditional CV method.更多还原
