首先介绍了三维(3D)图像骨架化相关问题描述与基本概念,接着从原理、实现技术及详细分类等方面综述了常用的三类3D图像骨架化方法,同时从算法的实现难易程度、骨架特性及运算速度等方面对三类方法进行了比较与分析.最后展望了3D骨架化方法今后的研究方向.
The problems and basic concepts related to 3D skeletonization are introduced. A summary to 3D skeletonization techniques, including principles, implementation strategies and classification in this field, is presented. Then evaluations on three typical methods are described. The prospects of the techniques are also discussed.
