Two-Character Motion Analysis and Synthesis

In this paper, we deal with the problem of synthesizing novel motions of standing-up martial arts such as Kickboxing, Karate, and Taekwondo performed by a pair of humanlike characters while reflecting their interactions. Adopting an example-based paradigm, we address three nontrivial issues embedded in this problem: motion modeling, interaction modeling, and motion synthesis. For the first issue, we present a semiautomatic motion-labeling scheme based on force-based motion segmentation and learningbased action classification. We also construct a pair of motion transition graphs, each of which represents an individual motion stream. For the second issue, we propose a scheme for capturing the interactions between two players. A dynamic Bayesian network is adopted to build a motion transition model on top of the coupled motion transition graph that is constructed from an example motion stream. For the last issue, we provide a scheme for synthesizing a novel sequence of coupled motions, gu...
