摘要

Methods, devices, media, and other embodiments are described for generating, modifying, and outputting pseudorandom animations that can be synchronized to audio data. In one embodiment, a computer animation model made up of comprising one or more control points is accessed by one or more processors, which associate motion patterns with a first control point of the one or more control points, and associate one or more speed harmonics with the first control point. A set of motion states is identify with a motion state for the combinations of possibilities, and a probability value is assigned to each motion state of the set of motion states. The probability value can be used to probabilistically determine a particular motion state to be part of displayed animation for the computer animation model.

說明書

Each motion state can, in various embodiments, be associated with a selectable energy threshold, such that the corresponding selectable probability weight for the corresponding motion state is based on audio characteristics of audio data used by the image modification data to animate the computer animation model within the frames of the video image. In such embodiments, a probability selection user interface further can include an energy threshold input for each motion state, and one or more selectable audio energy samples. In some such embodiments, a computer animation model comprises a two-dimensional overlay generated by analyzing content of the frames of the video image and replacing portions of the frames of the video image with one or more animation elements. In other embodiments, computer animation model comprises an overlay generated by analyzing content of the frames of the video image and replacing portions of the frames of the video image with a representation of a three-dimensional model comprising a skin over a skeleton model comprising the one or more control points.

Various example embodiments an methods are described above. It will be understood that, while specific structures and sets of operations are described, intervening or repeated structures and operations are possible within the scope of the embodiments described herein, and the specifically described examples are not exhaustive.
