Jaggies (staircasing effects) along slanted lines or curved edges are omnipresent in digital imaging. They are so widespread in digital display devices that very often they are associated with the modern "computerized" world (and sometimes even intentional ...
Suite au tremblement de terre en 2012, la ville de Mirandola a subi des endommagements remarquables, se trouvant dans la condition de se confronter à un centre-ville en grande partie détruit et d'en planifier la reconstruction. Le projet s'occupe de la rec ...
We study the design of sampling trajectories for stable sampling and reconstruction of bandlimited spatial fields using mobile sensors. As a performance metric we use the path density of a set of sampling trajectories, defined as the total distance travele ...
Research on conflict prevention has mainly focused on the causes of war and post-conflict reconstruction. Our knowledge on how civilians manage to contain violence in unstable and conflict environments is, however, very limited. This article aims to unders ...
This abstract presents the Tractometer evaluation system (www.tractometer.org) and how it was used to evaluate the entries of the ISBI 2013 HARDI Reconstruction Challenge to find the best local reconstruction methods of the contest. This abstract raises qu ...
We address the resolution of inverse problems where visual data must be recovered from incomplete information optically acquired in the spatial domain. The optical acquisition models that are involved share a common mathematical structure consisting of a l ...
We consider the task of recovering correlated vectors at a central decoder based on fixed linear measurements obtained by distributed sensors. A general formulation of the problem is proposed, under both a universal and an almost sure reconstruction requir ...
A comparison of algorithms for depth-of-field extension in the particular field of digital holographic microscopy is presented. Using the reconstruction properties of holography, a simple 3D reconstruction method from a single hologram is deducted. ...
This article extends the concept of it compressed sensing to signals that are not sparse in an orthonormal basis but rather in a redundant dictionary. It is shown that a matrix, which is a composition of a random matrix of certain type and a deterministic ...
Detailed reconstruction of the spatiotemporal history of embryonic cells is key to understanding tissue formation processes but is often complicated by the large number of cells involved, particularly so in vertebrates. Through a combination of high-resolu ...
