Robust Measurement Validation in Target Tracking Using Geometric Structure

Ji Won Yoon, Stephen J. Roberts

Abstract: Selection schemes for forming data validation regions for target tracking are discussed in this paper. We develop a novel algorithm, less sensitive to gate size than conventional approaches. This new gate selection method combines a conventional threshold based algorithm with a geometric metric measure based on the Voronoi diagram. An adaptive search based on the Voronoi measure is then used to select valid data points for target tracking.
