This paper studies how to improve the coverage of camera networks where the locations and orientations of the cameras can be adjusted. As the power energy limits the distance that each camera can move, the coverage problem is a constrained optimization. We provide three particle swarm optimization (PSO) algorithms for the problem, which are the penalty PSO,(More)
We propose a real-time multi-step view reconstruction algorithm and we tune its implementation to a virtual teleconference application. Theoretical motivations and practical implementation issues of the algorithm are detailed. The proposed algorithm can be used to reconstruct novel views at arbitrary poses (position and orientation) in a way that is(More)
—Aiming at improving the precision of nodes' localization, this paper analyses the source of the localization error when using the least square algorithm, and proposes the principle to choose the benchmark anchor nodes in reducing the power of equation. Based on this principle, the algorithm choosing the nearest node as the benchmark anchor node in LSM and(More)
