METHODS AND SYSTEMS FOR PERSONALIZED 3D HEAD MODEL DEFORMATION

An electronic apparatus performs a method of generating a three-dimensional (3D) head deformation model that includes: receiving a two-dimensional (2D) facial image; identifying a first set of keypoints in the 2D facial image based on some artificial intelligence (AI) models; mapping the first set o...

Zusammenfassung:An electronic apparatus performs a method of generating a three-dimensional (3D) head deformation model that includes: receiving a two-dimensional (2D) facial image; identifying a first set of keypoints in the 2D facial image based on some artificial intelligence (AI) models; mapping the first set of keypoints to a second set of keypoints based on a set of user-provided keypoint annotations located on a plurality of vertices of a mesh of a 3D head template model; performing deformation to the mesh of the 3D head template model to obtain a deformed 3D head mesh model by reducing the differences between the first set of keypoints and the second set of keypoints; and applying a blendshape method to the deformed 3D head mesh model to obtain a personalized head model according to the 2D facial image.
