A new edge-based interactive image segmentation method

摘要

This paper presents a new edge-based interactive image segmentation method. First an edge image is generated with an edge detector, and then primary object edges can be selected by separating the object and background edges. Finally we obtain the complete object edge by connecting broken object edges. In order to reduce the influence of the noise, image denoising can be done before the edge detecting. Natural and medical image segmentation demonstrates that our method incorporates the advantages of the automatic and manual image segmentation methods. For most of images, a little of manual object edge connection is needed to obtain object edges. It is an effective and feasible interactive image segmentation method.
