基于分水岭算法的交互式三维分割方法
Interactive three-dimensional segmentation based on watershed algorithm
摘要
Abstract
BACKGROUND: The accurate three-dimensional (3D)segmentation of humantissue can improve the accuracy of clinical diagnosis, the traditional gradient watershed segmentation has the over-segmentation problem which makes the 3D segmentation of human tiss ue hard to implement.OBJECTIVE: In order to segment human tissue's 3D structure and reduce the influence of the pseudo-minima points on image segmentation, to propose an interactive 3D segmentation method based on marker-controlled watershed algorithm. METHODS: The internal and external markers of CT sequence images were extracted, then the gradent images were modified to segment the images. According to the similarity of neighbouring slices, we segmented the 3D structure of humantissue using human-computer interactive method. We first selected a pointfrom the interested area in the f I rst s lice. Then we could extractthe interested area from the 3D slices by using the overlap relationship of tissues on continuous CT slices. RESULTS AND CONCLUSION: The marker-controlled watershed algorithm solves the over-s egmentation problem which segmentng the original gradient images meets. The proposed method makes it possible to make the further segmentation. The results suggest that, the segmented result using interactive3D segmentation based on watershed algorithm can clearly and accurately shows the 3D features of the tissue.关键词
