Analyzing and Tracking Burning Structures in Lean Premixed Hydrogen Flames [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2010 This paper presents topology-based methods to robustly extract, analyze, and track features defined as subsets of isosurfaces. First, we demonstrate how features identified by thresholding isosurfaces can be defined in terms of the Morse complex.
