Surface-to-Skeleton 3D Cephalometry: Estimating Hidden Skeletal Landmarks from CT-Derived External Soft-Tissue Surfaces
Tomoki Abe, Taiki Kanaya, Kazuki Saita +4
Existing 3D facial-landmark methods localize points on visible skin, but whether CT-defined internal skeletal landmarks can be inferred from external soft-tissue geometry remains u…
Profile-Specific 3DMM Regression from a Single Lateral Face Image
Taiki Kanaya, Hideo Saito
Single-image 3D face reconstruction is a core problem in computer vision, with important clinical applications such as cephalometric landmark analysis in orthodontics. Traditionall…
Disturbance-Free Surgical Video Generation from Multi-Camera Shadowless Lamps for Open Surgery
Yuna Kato, Shohei Mori, Hideo Saito +3
Video recordings of open surgeries are greatly required for education and research purposes. However, capturing unobstructed videos is challenging since surgeons frequently block t…
High-Quality Virtual Single-Viewpoint Surgical Video: Geometric Autocalibration of Multiple Cameras in Surgical Lights
Yuna Kato, Mariko Isogawa, Shohei Mori +3
Occlusion-free video generation is challenging due to surgeons' obstructions in the camera field of view. Prior work has addressed this issue by installing multiple cameras on a su…
Dense Depth from Event Focal Stack
Kenta Horikawa, Mariko Isogawa, Hideo Saito +1
We propose a method for dense depth estimation from an event stream generated when sweeping the focal plane of the driving lens attached to an event camera. In this method, a depth…
