Abstract. This paper describes Pittsburgh Pattern Recognition's participation in the face detection and tracking tasks for the CLEAR 2006 evaluation. We first give a system overview, briefly explaining the three main stages of processing: (1) frame-based face detection; (2) motionbased tracking; and (3) track filtering. Second, we summarize and analyze our system's performance on two test data sets: (1) the CHIL Interactive Seminar corpus, and (2) the VACE Multi-site Conference Meeting corpus. We note that our system is identically configured for all experiments, and, as such, makes use of no site-specific or domain-specific information; only video continuity is assumed. Finally, we offer some concluding thoughts on future evaluations. 1 System Description
