Method for Facial Animation

A method comprising:

• obtaining image data of a face of a user having a first expression;
• obtaining a user-specific expression model representative of a face of a user based on the image data;
• determining expression parameters for the user having a second expression, wherein the expression parameters are associated with the user-specific expression model and the second expression;
• determining animation parameters for a digital character based on the expression parameters and a pre-defined animation of a generic expression model;
• and
• animating the digital character based on the animation parameters.

A non-transitory computer readable medium comprising computer readable code executable by one or more processors to:

• obtain image data of a face of a user having a first expression;
• obtain a user-specific expression model representative of a face of a user based on the image data;
• and
• determine expression parameters for the user having a second expression, wherein the expression parameters are associated with the user-specific expression model and the second expression;
• determine animation parameters for a digital character based on the expression parameters and a pre-defined animation of a generic expression model;
• and
• animate the digital character based on the animation parameters.
