Locally Injective Parametrization With Arbitrary Fixed Boundaries

This algorithm for mapping a triangle mesh, which is homeomorphic to a disk, to a planar domain with arbitrary fixed boundaries allows the fixed boundary to intersect itself and is guaranteed to produce a mapping that is injective locally (if such a map exists).

Provably Good Planar Mappings

This paper introduces a method to interactively generate smooth, injective maps with guaranteed bounds on the distortion, using general basis functions.

Context-Based Coherent Surface Completion

A method for automatically completing missing regions of a triangle mesh, as might arise during 3D scanning, or archaeological excavation. The algorithm enforces a coherence objective within a global error minimization process.

Diffusion Pruning for Rapidly and Robustly Selecting Global Correspondences Using Local Isometry

This pruning technique for non-rigid shape correspondences uses diffusion to infer global isometric consistency from local isometry. It handles holes and globally non-isometric deformation, provided that the deformation is locally isometric. Significant improvements in accuracy and efficiency, and reduction of memory requirement are also achieved.

Feature Matching With Bounded Distortion

This paper considers the problem of finding a geometrically consistent set of point matches between two images. Given a set of candidate matches, possibly with many outliers, the approach seeks the largest subset of these correspondences that can be aligned perfectly with a bounded distortion deformation.
