Exploring Image Registration Techniques for Layered Sensing

摘要

In this paper we evaluate several methods to register and stabilize a motion imagery video sequence under the layered sensing construction. Layered sensing is a new construct in the repertoire of the US Air Force. Under the layered sensing paradigm, an area is surveyed by a multitude of sensors at many different altitudes and operating across many modalities. This combination of sensors provides better insight into a situation than could ever be achieved with a single sensor. A fundamental requirement to utilize this technology is to first register and stabilize the data from each of the individual sensors. The contribution of this paper is to explore and provide a preliminary evaluation of techniques for image registration of Electro-Optical (EO) video sequences taken from Wide Area Persistent Surveillance (WAPS) platforms whose views are centered on a city. Additionally, evaluation metrics for such techniques are described and explored.
