Methods and systems for forming personalized 3D head and facial models

An electronic apparatus performs a method of customizing a standard face of an avatar in a game using a two-dimensional (2D) facial image of a real-life person that includes: identifying a set of real-life keypoints in the 2D facial image; transforming the set of real-life keypoints into a set of game-style keypoints associated with the avatar in the game; generating a set of control parameters of the standard face of the avatar in the game by applying the set of game-style keypoints to a keypoint to parameter (K2P) neural network model; and deforming the standard face of the avatar in the game based on the set of control parameters, wherein the deformed face of the avatar has the facial features of the 2D facial image.
