1. A method for generating a three-dimensional (3D) face comprising at least one deformed region, the method comprising:
obtaining a curvature exaggeration face from at least one region of a first 3D face;
obtaining a set of relative deformations from a first set of 3D caricatured faces and a second set of 3D faces, wherein the set of relative deformations are the 3D caricatured faces of the first set standardized using a standard deviation and a mean of the 3D faces of the second set;
obtaining a first relative deformation for the at least one region of the first 3D face, wherein the first relative deformation is obtained by a standardization of the at least one region of the first 3D face using the standard deviation and the mean of the 3D faces of the second set;
obtaining, based on the first relative deformation, at least one nearest relative deformation from the set of relative deformations;
determining a proportion exaggeration deformation from the at least one nearest relative deformation, wherein the proportion exaggeration deformation is a weighted average deformation from the at least one nearest relative deformation, based on a distance of the at least one nearest relative deformation to the first relative deformation; and
combining the curvature exaggeration face and the proportion exaggeration deformation for obtaining the at least one deformed region of the 3D face.
