Dengfeng Chen · Jisuanji gongcheng · 2012
In process of concrete CT image segmentations,the compute complexity is higher when belief messages are transmitted.Aiming at this problem,this paper proposes a fast segmentation algorithm based on multiscale belief propagation.According to the feature of belief propagation algorithm,it structures grid figure with pyramid shape for message transmission,so as to speed up the convergence speed and reduce iteration times.It uses ambigram technology to reduce faith the quantity of information.Experimental results show that the proposed method can improve efficiency and precision of the image segmentation.
