In this paper, the honey bee mating optimization (HBMO) algorithm is used to improve the detection of the concave region connected with the control points of active contour. In the traditional active contour model (ACM) method, the updating of control point is based on its local energy within a small searching window. As a result, it always results in the failure of precisely searching the boundary...
Road extraction is one of the most active research fields in information extraction from high-resolution remote sensing images. It is not only of great theoretical value, but also of a broad prospect. This paper describes the general approaches of Semi-Automated Road Extraction, presents the latest research work and the typical methods from all over the world and analyzes its characteristics. Finally...
In this paper, a level set method with shape model is proposed for image segmentation. Because the level set model proposed by Chan and Vese can not work well on some specific shape, this paper adds the shape knowledge into the segmentation method. The Chan-Vese level set model is applied to get initial segmentation. And then the position and the size of the pre-segmented region will be calculated...
In this article, an integrated method, named GC-CV, was developed and applied to image segmentation. The proposed method combines graph cut method and the simplified Mumford-Shah model (C-V model), and takes the advantages of both. In this paper, the proposed GC-CV method is put to test in its three different operational modes. The first mode is the segmentation of binary images using GC-CV directly...
