Evaluation of motion retargeting using spacetime constraints

Abstract

This thesis report describes the evaluation of the retargeting method “Retargetting Motion to New Characters” as introduced by Gleicher. Our description of the method shows more details than the original paper does. This report also grants more background information about differentiation a constraint function, using either divided differentiation or automatic differentiation. Furthermore the for the interpolation method, a B-spline, is explained more extensively. Explaining the range of influence of B-spline control points and calculating a point on the B-spline locally without evaluating the whole spline. Finally experiment have been executed on our own implementation of this method. The experiments evaluate the method on its performance with different kinds of constraints, different motions and different scalings. The resulting motions of those experiments are inspected visually on quality.
