Controlled-topology filtering
YI Gingold, D Zorin - Proceedings of the 2006 ACM symposium on Solid …, 2006 - dl.acm.org
Many applications require the extraction of isolines and isosurfaces from scalar functions
defined on regular grids. These scalar functions may have many different origins: from MRI and …

Tracking flame base movement and interaction with ignition kernels using topological methods
We segment the stabilization region in a simulation of a lifted jet flame based on its topology
induced by the Y OH field. Our segmentation method yields regions that correspond to the …

Connectivity-aware Graph: A planar topology for 3D building surface reconstruction
S Yang, G Cai, J Du, P Chen, J Su, Y Wu… - ISPRS Journal of …, 2022 - Elsevier
Multi-view Stereo (MVS) meshes suffer from occlusions or missing data, making most
surface reconstruction methods invalid. Due to data imperfections, existing methods, just like …

Topology exploration with hierarchical landscapes
Topological landscapes have been proposed as a visual metaphor for contour trees that does
not require an understanding of the theory involved in defining contour trees. The idea is …

Farthest Voronoi diagrams under travel time metrics
Given a set of roads in the plane with assigned speed, a traveler is assumed to move at the
specified speed along each road, and at unit speed out of the roads. We are interested in the …
