Abstract
This paper proposes methods for tracking of hierarchical 2D content-based mesh representations. We introduce new techniques to maintain the initial mesh hierarchy and topology during tracking by imposing certain constraints at each stage of the procedure. Experimental results are presented to compare the tracking performance of hierarchical versus non- hierarchical mesh representations. The results show that hierarchical tracking outperforms single-level tracking in case there is significant motion.
