In this paper, we propose to capture image-based rendering scenes using a novel approach called active rearranged capturing (ARC). Given the total number of available cameras, ARC moves them strategically on the camera plane in order to minimize the sum of squared rendering errors for a given set of light rays to be rendered. Assuming the scene changes slowly so that the optimized camera locati...

Science serves its readers as a forum for the preselntation and discussion of important issues rclated to the advancement of science, including the presentation of minority or conflicting points of view, rather than by publishing only material on which a consensus has been reached. Accordingly, all articles ptublished in Science-including editorials, news and comment, and book reviews -arc sign...

In this paper we address the Sensor Location Problem, that is the location of the minimum number of counting sensors, on the nodes of a network, in order to determine the arc flow volume of all the network. Despite the relevance of the problem from a practical point of view, there are very few contributions in the literature and no combinatorial analysis is performed to take into account partic...

In an earlier paper [Kosch et al., 1998], simultaneous all-sky TV imager and Scandinavian Twin Auroral Radar Experiment (STARE) observations of an ionospheric plasma vortex located poleward of an auroral arc were presented. The vortex is associated with a sudden brightening of the arc and corresponds to an ionospheric region of diverging horizontal electric fields, which is equivalent to a down...

We study a system of self-propelled agents with the restricted vision. The field of vision of each agent is only a sector of disk bounded by two radii and the included arc. The inclination of these two radii is characterized by the view angle. The consideration of restricted vision is closer to the reality because natural swarms usually do not have a panoramic view. Interestingly, we find that ...
