CEPHA29: Automatic Cephalometric Landmark Detection Challenge 2023 [PDF]

arXiv, 2022
Quantitative cephalometric analysis is the most widely used clinical and research tool in modern orthodontics. Accurate localization of cephalometric landmarks enables the quantification and classification of anatomical abnormalities, however, the traditional manual way of marking these landmarks is a very tedious job.
