Active contours based on weighted gradient vector flow and balloon forces for medical image segmentation [PDF]

, 2014
Active contours, or snakes, have been widely used for image segmentation purposes. However, high noise sensitivity and poor performance over weak edges are the most acute issues that hinder the segmentation accuracy of these curves, particularly in ...
