A Unifying Theoretical Framework for Region Tracking

Technical Report CSE-2013-04

February 8 2013


Visual region-based tracking is a heavily researched general approach to following a target across a temporal image sequence. Little research, however, has addressed the interelationships of the various approaches at a theoretical level. In response to this situation, the present report describes a unifyting framework for a wide range of region trackers in terms of the amount of spatial layout that they maintain in the target representation. This framework yields a general notaion from which any of these trackers can be instantiated. To illustrate the pratical utility of the framework, a range of region trackers are instantiated within its formalism and used to document empirically the impact of maintaining variable amounts of spatial information during target tracking.
