Robust Computation of 3D Apollonius Diagrams
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Apollonius diagrams, also known as additively weighted Voronoi diagrams, are an extension of Voronoi diagrams, where the weighted distance is defined by the Euclidean distance minus the weight. The bisectors of Apollonius ...
SRF-Net: Spatial Relationship Feature Network for Tooth Point Cloud Classification
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
3D scanned point cloud data of teeth is popular used in digital orthodontics. The classification and semantic labelling for point cloud of each tooth is a key and challenging task for planning dental treatment. Utilizing ...
A Deep Residual Network for Geometric Decontouring
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Grayscale images are intensively used to construct or represent geometric details in field of computer graphics. In practice, displacement mapping technique often allows an 8-bit grayscale image input to manipulate the ...
From 2.5D Bas‐relief to 3D Portrait Model
(© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
In contrast to 3D model that can be freely observed, p ortrait bas‐relief projects slightly from the background and is limited by fixed viewpoint. In this paper, we propose a novel method to reconstruct the underlying 3D ...
