摘要

拓扑属性是对数字对象识别有用的全局特征。例如，对于具有复杂形状而不能分解为有意义的简单部分的对象，情况就是如此。在三维二值图像的情况下，拓扑特征是对象组件、空腔和隧道。虽然物体组件和空腔很容易定义和识别，但据我们所知，没有计算上方便的方法可以找到隧道。本文的目的是通过提供一种方便的方法来检测和表示三维物体中的隧道，从而填补这一空白。

Finding cavities and tunnels in 3D complex objects

Topological properties are global features that can be useful for recognition of digital objects. For example, this is the case for objects having a complex shape without being decomposable into meaningful simple parts. In the case of 3D binary images, topological features are the object components, cavities, and tunnels. While object components and cavities are easy to define and identify, to our knowledge, no computationally convenient way to find tunnels is available. The aim of the paper is to fill this gap by presenting a convenient procedure to detect and represent tunnels in 3D objects.
