We present an approach to activity discovery, the unsupervised identification and modeling
of human actions embedded in a larger sensor stream. Activity discovery can be seen as the …

We propose an adaptive approach for the fast reconstruction of isosurfaces from regular
volume data at arbitrary levels of detail. The algorithm has been designed to enable real …

3-D scene representation is utilized during scene extraction, modeling, transmission and
display stages of a 3DTV framework. To this end, different representation technologies are …

This paper presents a novel algorithm for generating a watertight level-set from an octree.
We show that the levelset can be efficiently extracted regardless of the topology of the octree …

In this paper we survey some of the major data structures for encoding Level Of Detail (LOD)
models. We classify LOD data structures according to the dimensionality of the basic …

Multiresolution meshes are a common basis for building representations of a geometric
shape at different levels of detail. The use of the term multiresolution depends on the remark …

In Geography and GIS, surfaces can be analysed and visualised through various data
structures, and topological data structures describe surfaces in the form of a relationship …

The reconstruction of isosurfaces from scalar volume data has positioned itself as a
fundamental visualization technique in many different applications. But the dramatically …

At the origin of this thesis stood the own painful experience with the difficulties of develo**
and reusing scientific software, even if the underlying mathematical problems solved by the …
