摘    要: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邻域超图 ,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 ,也具有良好的分割效果 .

关 键 词:多分辨率小波分析  空间结构特征  邻域超图  图象分割

Abstract:In this paper, an approach for image segmentation incorporating the theory of hypergraph with the spatial frequency features of image is proposed. Based on the multiresolution wavelet analysis and the theory of Gaussian Markov random field, the features characterizing the local spatial structure of image are extracted, a neighborhood hypergraph with respect to the similarities of the features is constructed, segmentation is implemented via the adapted Covering Selection algorithm.The adaptability and reliability have been tested through simulations. The approach is effective for segmentation of images with low SNR.
Keywords:Multiresolution wavelet analysis   Spatial structure feature   Neighborhood hypergraph   Image segmentation
