Adaptive constraints for feature tracking

By K. I. Hodges

Abstract

In this paper extensions to an existing tracking algorithm are described.\ud These extensions implement adaptive tracking constraints in the form\ud of regional upper-bound displacements and an adaptive track smoothness\ud constraint. Together, these constraints make the tracking algorithm\ud more flexible than the original algorithm (which used fixed tracking\ud parameters) and provide greater confidence in the tracking results.\ud The result of applying the new algorithm to high-resolution ECMWF\ud reanalysis data is shown as an example of its effectiveness
