Ternary phase-amplitude filters (encoding only -1, 0, and +1 modulation values) have been designed to respond to geometric features oftargetobjectsin scenes, forexample thewhecls on atruck. The filtersarebasedongenenc models involving only a few parameters, whose adjustment allows the model to be matched to different instances ofthe feature (e.g., different size wheels). The formulation ofthe model-based filtersand theircorrelation performance usingrealistic images ofvehicles in clutter backgrounds willbepresented. Candidatepost-processing approaches to exploitthe correlation results fortargetrecognition will be discussed.
