RRT-based strategies for sensor-based exploration
—Real mobile robots should be able to build an abstract representation of the physical environment, in order to navigate and to work in such environment. We present a method for ...

Polytope kernel density estimates on Delaunay graphs
We present a polytope-kernel density estimation (PKDE) methodology that allows us to perform exact mean-shift updates along the edges of the Delaunay graph of the data. We discuss...

Optimal Isosurface Extraction from Irregular Volume Data
A method is proposed which supports the extraction of isosurfaces from irregular volume data, represented by tetrahedral decomposition, in optimal time. The method is based on a d...
