Multi-scale and Snakes for Automatic Road Extraction
Abstract. This paper proposes an approach for automatic road extraction in aerial imagery which exploits the scale-space behavior of roads in combination with geometric constrained...

Efficient Computation of Morse-Smale Complexes for Three-dimensional Scalar Functions
The Morse-Smale complex is an efficient representation of the gradient behavior of a scalar function, and critical points paired by the complex identify topological features and th...

Combinatorial Surface Integration
Graph-Spectral surface integration techniques construct an integration path assuming that the surface contains a path along which the integration error is minimal. This paper pres...

A Surface Displaced from a Manifold
We present a new surface representation scheme based on a manifold structure and displacement functions. Given a geometric model represented as a point cloud, we construct a domain...

Automatic Blocking Scheme for Structured Meshing in 2d Multiphase Flow Simulation
We present an automatic algorithm to construct blocking scheme for multiblock structured meshes in 2D multiphase flow problems. Our solution is based on the concepts of medial ax...
