基于灰度分布匹配的多模态脑部MR图像肿瘤分割算法
Tumor segmentation on multi-modality brain MR image based on grayscale distribution matching
摘要
Abstract
For the issue that the tumor segmentation on multi-modality brain magnetic resonance (MR) image,this paper proposed a tumor segmentation algorithm based on grayscale distribution matching.Firstly,it used the distribution of non-parametric model of image grayscale intensity to describe the normal region of the current image.Then,it calculated the global similarity between tumor image regions to find the sub-regions whose gray-level distribution was most consistent with the learning model.At the same time,it used a smooth operation to avoid the existence of the isolated region.Finally,it processed the FLAIR modal images to isolate the brain edema regions,and finally to obtain the accurate boundaries of brain tumor regions.Experiments are performed on multi-modality brain tumor image database:BraTS 2012,and the results show that the algorithm can accurately and completely separate the tumor region.关键词
