Two present variational level set models of image segmentation are analyzed,then based on them a new variational level set method is proposed to integrate the image information from both boundary gradient and region.This method succeeds the advantages of these two above-mentioned models while overcomes their disadvantages.Meanwhile,the method adopts the implicit iterative numerical algorithm,which can not only guarantee the stability but also improve the convergence speed of the proposed model.Experiments illustrate that the method proposed has the ability to segment images with different types and results in rapid,stable,exact and robust effects.
