基于模糊和多分辨分析的骨肿瘤X光图像分割

SEGMENTATION OF X RAY IMAGES OF OSTEOMA BASED FUZZY AND MULTIRESOLUTION ANALYSIS

根据骨肿瘤 Ｘ 光图像的局部区域特性，采用多分辨图像处理和模糊聚类方法对它进行分割．分割由以下几步来完成：（１） 将图像分成相互交叠的子图像块；（２） 采用基于模糊连接的多分辨图像处理算法对各子图像进行处理；（３） 对各子图像的处理结果利用模糊聚类方法选择阈值．该方法应用于临床骨肿瘤 Ｘ光图像，获得了良好的分割结果．

In this paper, X ray images of osteoma are segmented by using multiresolution image processing and fuzzy clustering algorithm according to the local properties of the image. The segmentation strategy is accomplished through following three steps: first, partitioning the image into a set of overlapping subimages; second, localizing the multiresolution image processing algorithm using fuzzy pyramid linking to subimages of the original image; finally, the output is thresholded using fuzzy clustering algorithm. The algorithm to clinic X ray images of osteoma is applied,and the satisfying segmentation results are got.
