A parametric motion concatenation method using cubic Bézier interpolation

Abstract

This paper presents a novel motion concatenation method for parametric motion synthesis techniques. First, motion groups are created based on the actions in each motion. We then extract all of the parameters that control the synthesized motions. To connect the motion groups, we propose a motion concatenation algorithm based on cubic Bézier interpolation that can be used to connect any pair of motions. All of the poses are pre-calculated before interpolation, so that the concatenated motions can be synthesized rapidly during the concatenation phase. Although there is no intersection region between the parameter spaces, the proposed method guarantees that transitions between motions can be generated for any consecutive motions, which is a problem found in existing methods.
