基于改进活动轮廓模型的图像分割
Image Segmentation Based on Improved Active Contour Model
摘要
Abstract
In order to overcome the problem of weak boundary and intensity inhomogeneity, a region-based active contour model for image segmentation is proposed in this paper. Using the global and local image information as the energy term driving evolution of active contour to the objective boundaries can effectively segment images with intensity inhomogeneity. In order to segment the image fast and accurately,the length term and penalty are incorporated into the energy equation. By adopting gradient descent method, the minimization of the energy equation can be given. Segmentation tests demonstrate that the proposed method can segment images with intensity inhomogeneity, needs less iteration and few iteration times,and is less sensitive to the location and size of the initial contour when is compared with the Local Binary Fitting( LBF) model and the Local Image Fitting( LIF) model.关键词
