New image segmentation model based on the level set method
Wang Wei-we · Journal of Xidian University · 2013
A novel variational model based on the level set method is proposed.In the model,we introduce a nonconvex regularizer which performs better than the convex ones on protecting edges.On the other hand,the nonconvex regularizer is designed to provide a force which can help the evolution of the level set function.The Nesterov algorithm is introduced to implement the model.Experiments demonstrate the advantages of the proposed method over the Chan-Vese model in terms of both efficiency and accuracy.
