一种基于一致性邻域超图模型的图象分割方法

提出了一种将超图理论与图象的空－频域特征分析相结合的图象分割方法，该方法是基于图象的多分辨率小波分析及高斯－马尔可夫随机场理论，在抽取一组反映图象局部空间结构信息的特征矢量基础上，根据同一区域的象素具有相似的特征矢量的原则，将图象转换为一个关于特征相似性测度的领域超图，再利用覆盖－选择算法对该超图进行分割的方法，实验证明，该方法具有较好的稳定性和适应性，尤其对于一些信噪比较低的图象，也具有良好的分

An Approach for Image Segmentation Based onthe Homogeneous Neighborhood Hypergraph

In this paper, an approach for image segmentation incorporating the theory of hypergraph with the spa-tial-frequency features of image is proposed. Based on the multiresolution wavelet analysis and the theory of Gaus-sian-Markov random field, the features characterizing the local spatial structure of image are extracted, a neigh-borhood hypergraph with respect to the similarities of the features is constructed, segmentation is implemented viathe adapted Covering-Selection algorithm.The adaptability and reliability have been tested through simulations.The approach is effective for segmentation of images with low SNR.
