摘要

在本文中,我们探索了在圆锥束计算机断层扫描图像中直接检测和标记牙齿的可能性,而无需对牙齿进行复杂的分割程序。我们使用圆形霍夫变换(CHT)来寻找牙齿的位置,使用强度水平来确定下颌骨的分割和变形模板来寻找牙齿在下颌骨上的最佳匹配位置。牙弓分为16个区域,牙齿在给定区域的位置被标记。

Teeth labeling from CBCT data using the Circular Hough Transform
In this paper, we explore the possibilities to detect and label straightforward the teeth in Cone Beam Computed Tomography images, without performing complex segmentation procedures on teeth. We are using the Circular Hough Transform (CHT) to find the teeth positions, segmentation using intensity level to determine the mandible and deformable templates to find the best fit position for the teeth on the mandible. The dental arch is split into 16 regions and the teeth are labeled by their position in a given region.
