We propose a method for exaggerating facial expressions derived from exaggeration mappings that transform facial motions into exaggerated motions. The exaggeration mapping of facial motions is defined by non-negative matrix factorization. Three-dimensional facial expressions are simulated using the exaggerating rate as an input value to convey the degree of variation. Experiments show the validity of the exaggeration mapping and facial expression simulations.
