Abstract: This paper reconstructs energy function by introducing external energy term of C-V model based on Li model. A variation level set model combining region with edge information is described, and it combines with the graph cuts theory based Graph Cuts Based Active Contours(GCBAC) algorithm. It proposes a method of object extraction which combines graph cuts with improved variation level set. This method enables two models organically combined to achieve the effect of mutual complementarities. Experimental results show that the proposed method has advantages of rapid, robust, and strong anti-noise and so on.
