Human motion retargeting with trajectory constraints

Abstract

The captured motion data can be utilized to produce kinds of animation for different characters. We propose a method to represent simulated motion, especially exaggerative motion by filtering the joint trajectories. The motion style is changed by shrinking or squashing the corresponding 3D trajectories. The similar but exaggerative motion with articulated constraints is generated by the inverse kinematic method. The motion of different characters can be combined to generate interactive human animation. Our method can also be utilized for motion segmentation.
