-VDD: Location Privacy Protection Based on Voronoi-Delaunay Duality
Wei Zeng, Abdur B. Shahid, Keyan Zolfaghari +3
To date, location privacy protection is a critical issue in Location-Based Services (LBS). In this work, we propose a novel geometric framework based on the classical discrete geom…
Spherical Parameterization Balancing Angle and Area Distortions
Saad Nadeem, Zhengyu Su, Wei Zeng +2
This work presents a novel framework for spherical mesh parameterization. An efficient angle-preserving spherical parameterization algorithm is introduced, which is based on dynami…
Registration of Volumetric Prostate Scans using Curvature Flow
Saad Nadeem, Rui Shi, Joseph Marino +3
Radiological imaging of the prostate is becoming more popular among researchers and clinicians in searching for diseases, primarily cancer. Scans might be acquired with different e…
The Unified Surface Ricci Flow
Min Zhang, Ren Guo, Wei Zeng +3
Ricci flow deforms the Riemannian metric proportionally to the curvature, such that the curvature evolves according to a heat diffusion process and eventually becomes constant ever…
Discrete Laplace-Beltrami Operator Determines Discrete Riemannian Metric
Xianfeng David Gu, Ren Guo, Feng Luo +1
The Laplace-Beltrami operator of a smooth Riemannian manifold is determined by the Riemannian metric. Conversely, the heat kernel constructed from its eigenvalues and eigenfunction…
Optimization of Surface Registrations using Beltrami Holomorphic Flow
L. M. Lui, T. W. Wong, W. Zeng +4
In shape analysis, finding an optimal 1-1 correspondence between surfaces within a large class of admissible bijective mappings is of great importance. Such process is called surfa…
