Adaptive Meshing Based on the Multi-level Partition of Unity and Dynamic Particle Systems for Medical Image Datasets [PDF]
International Journal Bioautomation, 2018 Surface meshes extracted from sparse medical images contain surface artifacts, there will produce serious distortion and generate numerous narrow triangle meshes.

The Shortest-Edge Duplication of Triangles
Mathematics, 2022 We introduce a new triangle transformation, the shortest-edge (SE) duplication, as a natural way of mesh derefinement suitable to those meshes obtained by iterative application of longest-edge bisection refinement. Metric properties of the SE duplication

Approximation of conformal mappings using conformally equivalent triangular lattices [PDF]
, 2015 Consider discrete conformal maps defined on the basis of two conformally equivalent triangle meshes, that is edge lengths are related by scale factors associated to the vertices.

Real-time scene reconstruction and triangle mesh generation using multiple RGB-D cameras
Journal of Real-Time Image Processing, 2017 We present a novel 3D reconstruction system that can generate a stable triangle mesh using data from multiple RGB-D sensors in real time for dynamic scenes.

A Combinatorial Solution to Non-Rigid 3D Shape-to-Image Matching [PDF]
, 2017 We propose a combinatorial solution for the problem of non-rigidly matching a 3D shape to 3D image data. To this end, we model the shape as a triangular mesh and allow each triangle of this mesh to be rigidly transformed to achieve a suitable matching to
