Active Contour Model Combined with Region Gradient
De Zhao, Chuanjiang He, Qiang Chen · Jisuanji gongcheng · 2012
Chan-Vese(C-V) model is computationally expensive and sensitive to initialization.In order to address these problems,a new active contour model combined with region gradient is proposed,which uses the gradient information in the interior of contour and the intensity information in the exterior of contour.Experimental results show that the proposed model can more quickly segment multi-phase images and allows more flexible initialization compared with the multi-phase CV model.
