Event based sensor versatility for long range surveillance imaging

Abstract

Event based image sensors (EBS), also known as neuromorphic cameras, create a stream of spatially tagged events corresponding to localised changes in intensity. From this stream, statistics of the turbulence altering the optical path may be extracted, and image restoration of the target is potentially more feasible because, contrary to a traditional image with a fixed exposure time, the events are causal, so spatial and temporal correlation, filtering, or tracking is possible. We explore this further with a long range surveillance system.
