Reconstructing facade semantic models using hierarchical topological graphs

HierS: hierarchical scaffold clustering using topological chemical graphs.

An exhaustive ring-based algorithm, HierS, has been developed in order to provide an intuitive approach to compound clustering for analyzing high-throughput screening results. The recursive algorithm rapidly identifies all possible ring-delimited substructures within a set of compounds. Molecules are grouped by shared ring substructures (scaffolds) so that common scaffolds obtain higher members...

Reconstructing and Correcting 3d Building Models Using Roof Topology Graphs

Refinement of Facade Models Using Image Sequences

Three dimensional building models have become important during the past years for visualization of touristic or historic objects. Detailed facade models are essential for realistic impressions on a terrestial observer. Such models require both a geometric component that describes the shape of the building or parts of it as well as a texture component that provides color information and depicts ...

Maximizing Adaptivity in Hierarchical Topological Models Using Extrema Trees

We present a highly adaptive hierarchical representation of the topology of functions defined over two-manifold domains. Guided by the theory of Morse-Smale complexes, we encode dependencies between cancellations of critical points using two independent structures: a traditional mesh hierarchy to store connectivity information and a new structure called extrema tree to encode the configuration ...
