基于高斯混合模型的腹主动脉图像分割
Image Segmentation of Abdominal Aorta Based on Gaussian Mixture Model
摘要
Abstract
To segment the abdominal aorta from CT images effectively, a improved segmentation algorithm based on Gaussian mixture model with space constraints is proposed.This algorithm integrates 3D neighborhood information into Gaussian mixture model, then estimates the parameters of Gaussian mixture model by using EM algorithm to segment the aorta from gray image of abdominal aorta.The experiments demonstrate that the proposed not only achieves the better segmentation of aortic branches, but also inhibits noise in images by considering the spatial neighborhood information.关键词
