Abstract

An animation system includes a video source filter, a tracker, a command recognizer, a character synthesizer, a character store, an overlay module, a video rendering filter and, optionally, a video store. The video source filter routes input video data to a tracker and a command recognizer. The command recognizer identifies predetermined patterns in the video input information and identifies the type of patterns. The tracker identifies the predetermined patterns in the video information and identifies the coordinates of the predetermined patterns. Based upon one or more types output by the command recognizer, the character synthesizer retrieves animation information from the character store. Places the retrieved animation information at coordinates identified by the tracker. The character synthesizer outputs animation information to the overlay module. The overlay module generates a composite video signal from the animation information and possibly other video information and now puts it to the video rendering filter. The video rendering filter outputs the composite video information to a video display.
