ABSTRACT:
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.
