A Topological Similarity Measure between Multi-Field Data using Multi-Resolution Reeb Spaces
Tripti Agarwal, Yashwanth Ramamurthi, Amit Chattopadhyay
Searching topological similarity between a pair of shapes or data is an important problem in data analysis and visualization. The problem of computing similarity measures using sca…
Topological Feature Search in Time-Varying Multifield Data
Tripti Agarwal, Amit Chattopadhyay, Vijay Natarajan
A wide range of data that appear in scientific experiments and simulations are multivariate or multifield in nature, consisting of multiple scalar fields. Topological feature searc…
Multivariate Topology Simplification
Amit Chattopadhyay, Hamish Carr, David Duke +2
Topological simplification of scalar and vector fields is well-established as an effective method for analysing and visualising complex data sets. For multi-field data, topological…
Certified Computation of planar Morse-Smale Complexes
Amit Chattopadhyay, Gert Vegter, Chee K. Yap
The Morse-Smale complex is an important tool for global topological analysis in various problems of computational geometry and topology. Algorithms for Morse-Smale complexes have b…
