Improved active contour model and its application in image segmentation
Qingbing Sang · Computer Engineering and Applications Journal · 2012
ACM(Active Contour Model),also called Snake model,is a usual image segmentation algorithm.In ACM based image segmentation,it is difficult to segment concavity edge and weak boundary region.In this paper,a local profile model is combined with original ACM model.It can confirm the real edge through comparing local profile and the pixels along the normal line of the key points.A new method to compute the curvature energy of the key points is also introduced which can fit the ACM model to concavity edge and improve the convergence speed.Experimental results validate the performance of improved ACM model.
