3D Shape Correspondence by Isometry-Driven Greedy Optimization
We present an automatic method that establishes 3D correspondence between isometric shapes. Our goal is to find an optimal correspondence between two given (nearly) isometric sha...

Regularizing 3D medial axis using medial scaffold transforms
This paper addresses a key bottleneck in the use of the 3D medial axis (MA) representation, namely, how the complex MA structure can be regularized so that similar, within-categor...

A Point-Matching Based Algorithm for 3D Surface Alignment of Drug-Sized Molecules
Abstract. Molecular shapes play an important role in molecular interactions, e.g., between a protein and a ligand. The `outer' shape of a molecule can be approximated by its s...
