This paper describes a novel real-time multi-spectral imaging capability for surveillance applications. The capability combines a new high-performance multi-spectral camera system with a distributed algorithm that computes a spectral-screening Principal Component Transform (PCT). The camera system uses a novel filter wheel design together with a high-bandwidth CCD camera to allow image cubes to...

In this paper we present techniques for detecting mines using data acquired at multiple wavelengths (multi-spectral) or at multiple times (multi-temporal). Both types of data employ vector-valued pixels, and therefore they have a common mathematical structure. For the multi-spectral data we show that the performance of standard algorithms can be improved signiÞcantly through spatial whitening w...

Abstract. Bridges and Reich suggested the idea of multi-symplectic spectral discretization on Fourier space [4]. Based on their theory, we investigate the multi-symplectic Fourier pseudospectral discretization of the nonlinear Schrödinger equation (NLS) on real space. We show that the multi-symplectic semi-discretization of the nonlinear Schrödinger equation with periodic boundary conditions ha...

Abstract Precisely localising solar Active Regions (AR) from multi-spectral images is a challenging but important task in understanding activity and its influence on space weather. A main challenge comes each modality capturing different location of the 3D objects, as opposed to typical imaging scenarios where all image bands observe same scene. Thus, we refer this special scenario multi-layer ...

We consider various relaying strategies for wireless networks by comparatively examining direct transmission, conventional relaying, and the novel concepts of cooperative relaying. The latter build on two inherent benefits of relaying systems: the spatial diversity offered by the relay channel, and the ability to exploit the broadcast nature of the wireless medium. Studied cooperative protocols...
