Double active contours
双活动轮廓模型*

One of the problems of active contour model is that how to choose the press force.If the press is too high,the active contour may across the weak boundary or the active contour can't be driven by press.This paper introduced a novel deformable model based on double active contours.Correspondence and constraint was set up between the inner and outer contours.Then the active contours evolved under the contour constraint.The novel deformable model could catch the boundary of the concave region,and determined we...
