An Exploration Framework to Identify and Track Movement of Cloud Systems
Found in: IEEE Transactions on Visualization and Computer Graphics
By Harish Doraiswamy,Vijay Natarajan,Ravi S. Nanjundiah
Issue Date:December 2013
pp. 2896-2905
We describe a framework to explore and visualize the movement of cloud systems. Using techniques from computational topology and computer vision, our framework allows the user to study this movement at various scales in space and time. Such movements could...
 
Output-Sensitive Construction of Reeb Graphs
Found in: IEEE Transactions on Visualization and Computer Graphics
By Harish Doraiswamy,Vijay Natarajan
Issue Date:January 2012
pp. 146-159
The Reeb graph of a scalar function represents the evolution of the topology of its level sets. This paper describes a near-optimal output-sensitive algorithm for computing the Reeb graph of scalar functions defined over manifolds or non-manifolds in any d...

A hybrid parallel algorithm for computing and tracking level set topology
Found in: 2012 19th International Conference on High Performance Computing (HiPC)
By Senthilnathan Maadasamy,Harish Doraiswamy,Vijay Natarajan
Issue Date:December 2012
pp. 1-10
The contour tree is a topological abstraction of a scalar field that captures evolution in level set connectivity. It is an effective representation for visual exploration and analysis of scientific data. We describe a work-efficient, output sensitive, and...
