Automatic Classification of Clouds on METEOSAT Imagery: Application to High-Level Clouds

Automatic Fusion of Photogrammetric Imagery and Laser Scanner Point Clouds

Fusion of close range photogrammery and the relatively new technology of terrestrial laser scanning methods offer new opportunities for photorealistic 3D models presentation, classification of real world objects and virtual reality creation (fly through). Laser scanning technology could be seen as a complement to close-range photogrammetry. For instance, terrestrial laser scanners (TLS) have th...

Automatic Generated Tag Clouds

This paper proposes a formal model for discussing the construction of tag clouds, applicable both to human beings and computer programs. From this model we also to propose a methodology for automatic generation of tag clouds, which aim to achieve results similar to the ones produced by human beings. We also present a specific implementation and describe some of our initial results. 1. Introduct...

Automated Detection of Clouds in Satellite Imagery

Distributed, application-level monitoring for heterogeneous clouds using stream processing

As utility computing is widely deployed, organizations and researchers are turning to the next generation of cloud systems: federating public clouds, integrating private and public clouds, and merging resources at all levels (IaaS, PaaS, SaaS). Adaptive systems can help address the challenge of managing this heterogeneous collection of resources. While services and libraries exist for basic man...

Recovery of Point Clouds on Surfaces: Application to Image Reconstruction

We introduce a framework for the recovery of points on a smooth surface in high-dimensional space, with application to dynamic imaging. We assume the surface to be the zero-level set of a bandlimited function. We show that the exponential maps of the points on the surface satisfy annihilation relations, implying that they lie in a finite dimensional subspace. We rely on nuclear norm minimizatio...
