Abstract:
Applying different styles of motion such as those related to gender, age and energy of the performer, are important themes in creating realistic animation. While typically different sets of motion sequences must be created for different styles, in this paper we present a technique for transferring motion styles across different sequences. This allows transforming the style of a motion while preserving the primary action class of the original motion. A mathematical model capable of defining both the action class and the style class is proposed and based on the model, the conversion data are computed. A series of piece-wise time warping procedures are conducted prior to employing the defined transformation function. Using this technique, there would be no need for a new set of motion data to be captured or keyframed as the original motion data can be altered to show the desired style.
