Computer Vision – ECCV 2016 Workshopsr conversion). With the hyper-raster the intersection sets, as needed for the determination of a topological relation between two objects, are calculated simply by logical joins of binary images. Without extending our model we can also compute further refinements of the relationships.

,The quad view data structure — a representation for planar subdivisions,y the quad view data structure. This algorithm is optimal for simply connected planar subdivisions: its time and storage requirements are linear in the size of the output subdivision. Finally we apply this overlay algorithm to implement locational vector-based map overlay operations.

Discovery of spatial association rules in geographic information databases,refined computations on small promising patterns), shared processing in the derivation of large predicates at multiple concept levels, etc. Our analysis shows that interesting association rules can be discovered efficiently in large spatial databases.

Accessing geographical metafiles through a database storage system,ored in files external to the database system, while indexing and query processing is carried out within the database system. We also report on our experiences in building such a prototype geographical metadata manager.

A 3D molecular surface representation supporting neighborhood queries,ted via complex pointers. However, we achieve a reduction of the space requirement by a factor of four. Finally, we investigate the time performance of our prototype which is based on an object-oriented database management system.
