    • A method and system for driving a graphical object based on a performance of an actor in a video stream. A plurality of key frames are selected in a calibration video stream, allowing animation control values to be defined, in accordance with artistic intent, for each of a set of control variables, corresponding to each of the key frames. Features of the actor in the calibration video stream are parameterized so as to obtain a vector of values of parameters for each frame of the calibration video stream, and, then, an array of distance vectors is derived, characterizing a distance between each pair of vectors of values of parameters among the video stream frames. The space of distance vectors is mapped into the set of control variables according to a mapping operation which is then applied to distance vectors derived from an actual performance video stream to obtain a time sequence of animation control values. Finally, an animation is created on the basis of applying the sequence of animation control values to the graphical object.
    • 一种用于基于视频流中的演员的表现来驱动图形对象的方法和系统。 在校准视频流中选择多个关键帧,允许根据艺术意图为与每个关键帧对应的一组控制变量中的每一个定义动画控制值。 将校准视频流中的演员的特征参数化,以获得校准视频流的每个帧的参数值的矢量,然后导出距离矢量的阵列,表征每对向量之间的距离 的视频流帧中的参数值。 根据映射运算将距离矢量的空间映射到控制变量集合中,然后将其应用于从实际演出视频流导出的距离矢量,以获得动画控制值的时间序列。 最后,在将动画控制值序列应用到图形对象的基础上创建动画。
