Patent ID: 8648866

Claim:
A facial animation system for producing 3-dimensional (3D) facial animation data in response to input video data, the input video data comprising a first frame, the facial animation system comprising: a display module; a transformation calculating module; a character acquiring device for performing data positioning and character sorting operations on the input video data to acquire first-layer character data according to the peak value of the variance of pixel data gray level of the input video data, for indicating a plurality of first-layer character points, and performing data positioning and character sorting operations on the first frame of the input video data to acquire first-layer model data; and a character verifying device for obtaining first-layer model outline data according to the first-layer model data, and obtaining first-layer character outline data according to the first-layer character data, the character verifying device further comparing the first-layer character outline data with the first-layer model outline data to judge whether the first-layer character outline data and the first-layer model outline data satisfy a judgment condition; wherein when the first-layer character outline data and the first-layer model outline data do not satisfy the judgment condition, the character verifying device outputs the first-layer character data, as output character data, to the transformation calculating module; wherein the transformation calculating module produces fundamental facial-mesh transformation data according to the output character data, and thus drives the display module to display the 3D facial animation data.
