AbstractThis paper presents the design of a new mote for distributed image sensing applications in wireless sensor networks. The processing and memory limitations in current mote designs are analyzed and a simple but powerful new platform is developed. The mote

Probabilistic image sensor fusion
free download

Abstract We present a probabilistic method for fusion of images produced by multiple sensors. The approach is based on an image formation model in which the sensor images are noisy, locally linear functions of an underlying, true scene. A Bayesian framework then

Active pixel CMOS image sensor with on-chip non-uniformity correction
