A Hu moment invariant as a shape circularity measure
Paul Rosin
Jan. 1, 2010
In this paper we propose a new circularity measure which defines the degree to which a shape differs from a perfect circle.
Detecting Design Intent in Approximate CAD Models using Symmetry
Ralph Martin
Jan. 1, 2010
Finding design intent embodied as high-level geometric relations between a CAD model's sub-parts facilitates various tasks such as model editing and analysis.
Automatic Range Image Registration in the Markov Chain
Yonghuai Liu
Jan. 1, 2010
In this paper, a novel entropy that can describe both long and short-tailed probability distributions of constituents of a thermodynamic system out of its thermodynamic limit is first derived from the Lyapunov function for a Markov chain.
Simulation of defects in bubble clusters
Jan. 1, 2010
Topological defects in a foam, either isolated (disclinations and dislocations) or in pairs, affect the energy and stress, and play an important role in foam deformation.
Active Contouring Based on Gradient Vector Interaction and Constrained Level Set Diffusion
Xianghua Xie
Jan. 1, 2010
This paper presents an extension of our recently introduced MAC model to deal with the initialization dependency problem that commonly appears in edge-based approaches.
Smooth Graphs for Visual Exploration of Higher-Order State Transitions
Mark Jones, Robert S Laramee
Nov. 1, 2009
In this paper, we present a new visual way of exploring state sequences in large observational time-series.
