A Framework for Model-Based Tracking Experiments in Image Sequences

Motris, an integrated system for model-based tracking research, has been designed modularly to study the effects of algorithmic variations on tracking results. Motris attempts to avoid introducing bias into the relative assessment of alternative approaches. Such a bias may be caused by differences of implementation and parameterization if the component approaches are evaluated in separate testing environments. Tracking results are evaluated automatically on a significant test sample in order to quantify the effects of different combinations of alternatives. The Motris system environment thus allows an in-depth comparison between the so-called ‘Edge-Element Association’ approach documented in Haag and Nagel (1999) and the more recent ‘Expectation-Maximization’ approach reported by Pece and Worrall (2002).
