We consider the hypersingular plasmonic surface modes that are supported by a 3D negative-permittivity circular conical tip and study how their occurrence depends on the opening angle and permittivity of the cone. A comparison to a 2D wedge is made.
Satellite images are useful to prevent major disasters and mitigate their impact on populations. Their analysis is usually manually conducted by operators. Automatic processing of very high resolution (VHR) images is critical when the images to analyse are acquired with different modalities: acquisition angles, spatial resolution, or even sensor; however, this situation is frequent in an operational...
A building damage assessment method applied to the case of the earthquake of Bam is proposed in this paper. It uses two very high resolution images and focuses on the footprints of the buildings. The need of an accurate registration of the buildings is demonstrated; a registration method that improved the damage assessment is proposed. It allows a classification performance of the buildings among...
Very high resolution images are particularly well adapted to damage assessment methodology in urban area because on one hand it allows an analysis focused on the buildings solely through an object-oriented analysis, and on the other hand it permits a quantitative evaluation of this damage assessment using a visually established ground truth. We propose in this paper a method of damage assessment that...
