Abstract :
We propose a method to extract motion individuality from the form of a sport expert and to apply it to figures that have different segment lengths. For this purpose, a standard motion is established by removing the subjective motion from an actor who conducts a sport skillfully, and the surface features (angular velocity and torque of the joint) are extracted for each joint angle difference in each animation frame between the original motion of the sports expert and the standard motion. The surface features and relative timing in the deep structure are transmitted to the characters having different segment lengths by applying them to a standard motion of the characters, which is also made by removing subjective motion in advance.
