In image processing, edge detection often makes use of integer-order differentiation
operators, especially order 1 used by the gradient and order 2 by the Laplacian. This paper …

Since 1999, very high spatial resolution satellite data represent the surface of the Earth with
more detail. However, information extraction by per pixel multispectral classification …

Quelles sont les informations contenues dans une image numérique? Comment et dans
quel cas les exploiter? Quels sont les moyens dont nous disposons pour en extraire de …

Image segmentation is a method to extract regions of interest from an image. It remains a
fundamental problem in computer vision. The increasing diversity and the complexity of …

Segmentation of time series of 3D cardiac images is clinically used for the assessment of the
mechanical function of the left ventricle. To take into account the 4D (3D+ T) nature of those …

Synthetic aperture radar provides broad-area imaging at high resolutions, which is used in
applications such as environmental monitoring, earth-resource mapping, and military …

Hypergraph theory as originally developed by Berge (Hypergraphe, Dunod, Paris, 1987) is a
theory of finite combinatorial sets, modeling lot of problems of operational research and …

The scope of this paper is to present the main tools of image analysis to investigate
materials and, specially, civil engineering ones. First the acquisition methods are described …

In this paper we present a segmentation algorithm, inspired from an image-processing
region-merging algorithm, for the delineation of discrete contiguous management zones in …

We evaluate the neutral pion photoproduction amplitude at threshold to one loop in chiral
perturbation theory. Virtual pions generated infrared singularities in the scattering amplitude …
