| 摘 要： | 为克服现有方法对数字人切片图像分割中人工参与的依赖,提出了一种基于连通域标记和K-均值聚类的数字人脑彩色切片图像分割方法.该方法首先通过连通域标记分割出脑组织的初始区域,再通过腐蚀操作精确提取脑组织,然后在RGB(红绿蓝)空间内借助直方图确定聚类中心,以欧几里得距离为判断标准实现对白质的K-均值聚类分割.采用首例中国女...

| Abstract: | In order to reduce the manual intervention involved in the existing segmentation methods of digital human slice images,an algorithm based on the connected component labeling and the K-means clustering is proposed.In this algorithm,first,the initial region of brain tissue is segmented via the connected component labeling and is refined via erosion.Then,a K-means clustering is adopted to extract the white matter,in which the color histogram is used to determine the clustering centers and the Euclidian distanc... |
