Automatic 3D Registration of Dental CBCT and Face Scan Data using 2D Projection Images

no code implementations17 May 2023 Hyoung Suk Park, Chang Min Hyun, Sang-Hwy Lee, Jin Keun Seo, Kiwan Jeon

A main contribution of this study is that the proposed method does not require annotated training data of facial landmarks because it uses a pre-trained facial landmark detection algorithm that is known to be robust and generalized to various 2D face image models.

Facial Landmark Detection

Fully automatic integration of dental CBCT images and full-arch intraoral impressions with stitching error correction via individual tooth segmentation and identification

no code implementations3 Dec 2021 Tae Jun Jang, Hye Sun Yun, Chang Min Hyun, Jong-Eun Kim, Sang-Hwy Lee, Jin Keun Seo

The proposed method is intended not only to compensate the low-quality of CBCT-derived tooth surfaces with IOS, but also to correct the cumulative stitching errors of IOS across the entire dental arch.

Automated 3D cephalometric landmark identification using computerized tomography

no code implementations16 Dec 2020 Hye Sun Yun, Chang Min Hyun, Seong Hyeon Baek, Sang-Hwy Lee, Jin Keun Seo

This paper presents a semi-supervised DL method for 3D landmarking that takes advantage of anonymized landmark dataset with paired CT data being removed.
