Schelling Points on 3D Surface Meshes

This paper investigates "Schelling points" on 3D meshes, feature points selected by people in a pure coordination game due to their salience.

Functional Maps: A Flexible Representation of Maps Between Shapes

A novel representation that generalizes the standard notion of a map as a pairing of points. By concentrating on finding correspondences between generic functions defined by the shapes,
this method creates a representation that is multiscale, compact, and amenable to efficient optimization.

Variational Mesh Decomposition

This variational algorithm for automatically decomposing 3D models into meaningful parts is developed using the Mumford-Shah model with spectral eigenvectors and handles partitioning and boundary smoothing simultaneously.

Sketch-Based Shape Retrieval

A system for 3D object retrieval based on sketched feature lines as input. For objective evaluation, the technique develops a benchmark based on a large number of sketches from human users. In the resulting comparison, this approach is significantly better than any other system described so far.
