Method for automatically producing video cartoon with superimposed faces from cartoon template

摘要

A method for automatically producing video cartoons with user-provided faces superimposed on cartoon characters is presented. A cartoon template stores the original video cartoon with unanimously-colored backgrounds and original cartoon characters' faces drawn following the guidelines of the invention. A background detection algorithm is used to detect the unanimously-colored backgrounds, while a face detection algorithm is used to detect the facial colors, facial expressions, sizes, rotations, positions and clippings of the original cartoon characters' faces. The detected unanimously-colored backgrounds may be replaced by optional user-provided backgrounds. User-provided faces with the best matching user-specified facial colors and expressions are superimposed over and on top of the corresponding original faces of the cartoon characters at the detected sizes, rotations, positions and clippings to produce the final video cartoon. The cartoon template can be distributed to many different users. Different users can add different user-provided faces, background images and audio to the same cartoon template to produce many different final video cartoons.
