An Illumination Model for a Skin Layer Bounded by Rough Surfaces
In this paper we present a novel illumination model that takes into account multiple anisotropic scattering in a layer bounded by two rough surfaces. We compute the model by a dis...

Temperature-Induced Domain Shrinking in Ising Ferromagnets Frustrated by a Long-Range Interaction
Abstract. We investigate a spin model in which a ferromagnetic shortrange interaction competes with a long-range antiferromagnetic interaction decaying spatially as 1 rd+ , d being...

Robust brain activation detection in functional MRI
Functional Magnetic Resonance Imaging (MRI) is today one of the most important non-invasive tools to study the brain from a functional point of view. The blood-oxygenation-level-d...

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...

Sequentially updated Probability Collectives
— Multi-agent coordination problems can be cast as distributed optimization tasks. Probability Collectives (PCs) are techniques that deal with such problems in discrete and conti...
