Voronoi-Based K Nearest Neighbor Search for Spatial Network Databases
A frequent type of query in spatial networks (e.g., road networks) is to find the K nearest neighbors (KNN) of a given query object. With these networks, the distances between ob...

Edge preserving spatially varying mixtures for image segmentation
A new hierarchical Bayesian model is proposed for image segmentation based on Gaussian mixture models (GMM) with a prior enforcing spatial smoothness. According to this prior, the...

Towards Model Checking Spatial Properties with SPIN
Abstract. We present an approach for the verication of spatial properties with Spin. We rst extend one of Spin's main property specication mechanisms, i.e., the linear-time...

Voronoi Tessellations and the Cosmic Web: Spatial Patterns and Clustering across the Universe
The spatial cosmic matter distribution on scales of a few up to more than a hundred Megaparsec1 displays a salient and pervasive foamlike pattern. Voronoi tessellations are a vers...

On the Relationship between Spatial Logics and Behavioral Simulations
Abstract. Spatial logics have been introduced to reason about distributed computation in models for concurrency. We first define a spatial logic for a general class of infinite-...
