Abstract:


    The problem of character locomotion synthesis is notorious for its high dimensionality and the nonlinear relationship between dimensions. However, many human motion activities lie intrinsically on low dimensional manifolds [Safonova et al. 2004] leading to significant data redundancy. Linear and non–linear methods for dimension reduction have been applied to the problem, but none of the existing approaches for dimensional reduction provide a physically–justified explanation for selected dimensions, instead they use general methods which employ numerical error analysis.
