摘　　要：人体行为分析与识别已经成为计算机视觉领域的一个热点问题,3维肢体分割在行为分析与识别中具有很重要的作用。这里提出了一种基于Reeb图的三维肢体分割的算法。对重构好的三维人体模型进行Reeb图提取,然后根据Reeb图节点的连接关系计算节点的度,关键节点定义为度非2的节点,再根据关键节点对Reeb骨架图进行分割,最后计算重构模型上点与Reeb骨架图的对应关系,反映射完成对人体模型的3维肢体分割。Human activity analysis and identification now becomes a hot issue in the area of computer vision.3D body segmentation plays an important role in body analysis and identification.In this paper,a body segmentation algorithm based on Reeb graph is proposed,which could effectively achieve human body segmentation.Reeb graph is extracted from a reconstructed human body,and then the Reeb graph skeleton is segmented.The corresponding relationship between reconstructed human body and Reeb graph framework is calculated,and inverse mapping is conducted,thus to achieve 3D body segmentation.
