A geometric active contour model without re-initialization for color images is proposed in this paper. It combines directional information about edge location based on local squared contrast as a part of driving force, together with the improved geodesic active contour containing Bayes error based statistical region information as well as an extra term that(More)
In this paper, we present a new variational formulation of geometric snake for image segmentation. Our formulation includes an internal energy term that penalizes the deviation of the level set function from a signed distance function and stopping term related to a particular segmentation of the image instead of gradient. They force the level set function(More)
