Pose-Aware Instance Segmentation Framework from Cone Beam CT Images for Tooth Segmentation
[article]
2020
arXiv
pre-print
Preserved Fulltext
Individual tooth segmentation from cone beam computed tomography (CBCT) images is an essential prerequisite for an anatomical understanding of orthodontic structures in several applications, such as tooth ...
The primary significance of the proposed method is two-fold: 1) an introduction of pose-aware VOI realignment followed by a robust tooth detection and 2) a metal-robust CNN framework for accurate tooth ...
