Abstract Based on previous knowledge and region information, a novel parametric active contour model (Snake model) for image segmentation to ambiguous edge is described in this paper. In the proposed model, constant force in the balloon snake model is replaced by variable force which incorporates with previous knowledge and two regions information of foreground and background. Experiments prove that the proposed model is robust to initial contour places and it can segment ambiguous edge image automatically. In addition, result of segmentation to two regions that have identical mean and different variation is correct.
