Automatic 3D acquisition devices (often called 3D scanners) allow to build highly accurate models of real 3D objects in a cost-and time-effective manner. We have experimented this technology in a particular application context: the acquisition of Cultural Heritage artefacts. Specific needs of this domain are: medium-high accuracy, easy of use, affordable(More)
This paper deals with the parallelization of Delaunay triangulation, a widely used space partitioning technique. Two parallel implementations of a three{dimensional incremental construction algorithm are presented. The rst is based on the decomposition of the spatial domain, while the second relies on the master{slaves approach. Both parallelization(More)
—This paper presents a new low-complexity H.264 encoder for Unmanned Aerial Vehicles (UAV) applications. Standard video coding systems currently employed in UAV applications do not rely on some peculiarities in terms of scene 3D model and correlation among successive frames. In particular, the observed scene is static, i.e. the camera movement is dominant,(More)
In this paper we propose an innovative video-based architecture aimed to monitor elderly people. It is based on cheap devices and open-source libraries and preliminary tests demonstrate that it manages to achieve a significant performance. The overall architecture of the system and its implementation are shortly discussed from the point of view of the(More)
A Vehicular Addhoc Network (VANET) is composed of vehicles, equipped with short range wireless interr faces, which collaborate to form a temporary distribb uted network enabling communications with other vehicles (or road infrastructure nodes) located in line of sight or even out of the radio range (if a multiihop network is built among vehicles).(More)
