Application of geodesic active contours based on total variation denoising

Although the classical geodesic active contour can deform an initial curve towards the boundary of the object to be detected,but the Gaussian regularization that has the property of the isotropic diffusion may simultaneously blur the edge or boundry of the objects and make the curve propagating unstable which can lead to a time-consuming propagation.This paper introduced a geodesic active contour model based on total variation denoising to solve the problem mentioned above.Total variation model can smooth out the noises in image,but it may simultaneously preserve and sharp the edge of the objects.Experimental results of applying the proposed method in noising images show that it yields good effect and saves time.
