1. A processor-implemented method comprising:
obtaining an input image including a face of a user;
extracting a feature from the input image;
estimating a facial expression of the input image and an individual expressiveness of the facial expression of the input image corresponding to a determined expression intensity of the facial expression based on the extracted feature;
normalizing the individual expressiveness of the facial expression of the input image to a universal expressiveness; and
recognizing the facial expression based on the universal expressiveness,
wherein the normalizing of the individual expressiveness normalizes an individual expressiveness of the user to a universal expressiveness based on a relative difference in expressiveness between users with respect to a same expression.
