Traditional level set methods could not deal with the segmentation of overlapped objects and the ones having the similar gray value with background, since these methods just take image data into consideration. Aiming for this problem, we propose a new edge-and region-based level set method for image segmentation. Our method firstly fuses the regional information into the edge-based level set method, and then incorporates shape priors to design a new level set method with shape priors. The comparison results show that the proposed method can segment the overlapped objects better and also achieve better performance on the objects with the similar gray value as background since it integrates multiple kinds of information together.
