Camera Network Coverage Improving by Particle Swarm Optimization

This paper studies how to improve the field of view (FOV) coverage of a camera network. We focus on a special but practical scenario where the cameras are randomly scattered in a wide area and each camera may adjust its orientation but cannot move in any direction. We propose a particle swarm optimization (PSO) algorithm which can efficiently...

X-Ray image denoising with directional support value transform

Under the support vector machine framework, the support value analysis-based image fusion has been studied, where the salient features of the original images are represented by their support values. The support value transform (SVT)-based image fusion approach have demonstrated some advantages over the existing methods in multisource image...

Real-Time Multi-Step View Reconstruction for a Virtual Teleconference System

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...
