MS-COOT: Comparing Morse-Smale Complexes with Co-Optimal Transport
Guangyu Meng, Mingzhe Li, Erin Wolf Chambers
Understanding and comparing structures in scalar fields is a central challenge in scientific visualization, with applications ranging from feature analysis to temporal and structur…
Spatiotemporal Detection and Uncertainty Visualization of Atmospheric Blocking Events
Mingzhe Li, Peer Nowack, Bei Wang
Atmospheric blocking events are quasi-stationary high-pressure systems that disrupt the typical paths of polar and subtropical air currents, often producing prolonged extreme weath…
Extremely Scalable Distributed Computation of Contour Trees via Pre-Simplification
Mingzhe Li, Hamish Carr, Oliver Rübel +2
Contour trees offer an abstract representation of the level set topology in scalar fields and are widely used in topological data analysis and visualization. However, applying cont…
Tracking Low-Level Cloud Systems with Topology
Mingzhe Li, Dwaipayan Chatterjee, Franziska Glassmeier +2
Low-level clouds are ubiquitous in Earth's atmosphere, playing a crucial role in transporting heat, moisture, and momentum across the planet. Their evolution and interaction with o…
Distributed Augmentation, Hypersweeps, and Branch Decomposition of Contour Trees for Scientific Exploration
Mingzhe Li, Hamish Carr, Oliver Rübel +2
Contour trees describe the topology of level sets in scalar fields and are widely used in topological data analysis and visualization. A main challenge of utilizing contour trees f…
