一种集成模糊特征的测地线主动轮廓模型的图像分割

A Fuzzy Feature Integrating to Geodesic Active Contour Model for Image Segmentation

构建有模糊特征控制的曲线法向力场集成到测地线主动轮廓模型,使得该模型能包含更多的图像分割信息。当用模糊特征表示图像区域信息时,改进模型保持了原来模型具有边缘指示特性,同时具有区域特征一致性的分割性能。改进模型提高了演化曲线抓取感兴趣目标的范围和提取凹凸区域的能力,可以适应对弱边缘、噪声干涉图像的分割。图像分割的实验说明新的模型对图像分割具有良好的性能。

It has been integrated into geodesic active contour model for the image segmentation that the fuzzy feature vector governs the normal force of curve. The modified model may contain more information of image segmentation. When fuzzy feature represents region information, the modified model has performance of region feature uniform in all the same edges indication for segmentation image. This method has a large capture range of interested region, improves performance of segmenting concave and convex objects and provides an accurate segmentation to weak edges and noise image. Experimental results of applying new scheme to real images demonstrate its segmentation power.
