Data-parallel primitives for performing operations on the PM1 quadtree and the bucket PMR quadtree are presented using the scan model. Algorithms are described for building these ...
When reflecting on information, spatial hypermedia users express their understanding of the information’s structure visually. In order to facilitate this process, spatial hyperm...
Clustering algorithms typically operate on a feature vector representation of the data and find clusters that are compact with respect to an assumed (dis)similarity measure betwee...
While realistic illumination significantly improves the visual quality and perception of rendered images, it is often very expensive to compute. In this paper, we propose a new al...
Background: Quality-control is an important issue in the analysis of gene expression microarrays. One type of problem is regional bias, in which one region of a chip shows artifac...
