New Variational Model for Image Segmentation
一种新变分方法在图像分割中的应用

Due to traditional variational level set for image segmentation with slowly computing efficiency, a new varitional model(PDE) was proposed. Firstly, the energy function was modified, then the minimization problem was transformed to convex optimization problem via convex relaxation technictue,and a new auxiliary variable was introduced,at last, the additive operator splitting(AOS) numerical algorithm was applied. The effective results show that the proposed model for image segmentation is feasible and performs better than conventional variatioanl model.
