Description
Summary:In this paper, a new geometric snake model is proposed, based upon techniques of curve evolution and the utilization of gradient information and region information simultaneously. This model successfully solves the boundary leakage problem. With the help of a hierarchical approach, it can handle complicated cases, such as triple junctions. Furthermore, it supports vector-valued images and can be easily extended to handle color and textured images. Experimental results demonstrate the model's power in image segmentation.
