应用不同的运动风格，例如与表演者的性别、年龄和精力相关的运动风格，是创建逼真动画的重要主题。虽然通常必须为不同的风格创建不同的运动序列集，但在本文中，我们提出了一种在不同序列之间转移运动风格的技术。这允许变换运动的风格，同时保留原始运动的主要动作类。提出了能够定义动作类和风格类的数学模型，并基于该模型计算转换数据。在使用定义的变换函数之前执行一系列分段时间扭曲过程。使用这种技术，不需要捕获一组新的运动数据或设置关键帧，因为可以更改原始运动数据以显示所需的风格。
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.
