Abstract
An electronic apparatus performs a method of constructing a facial position map from a two-dimensional (2D) facial image of a real-life person that includes: generating a coarse facial position map from the 2D facial image; predicting a first set of keypoints in the 2D facial image based on the coarse facial position map; identifying a second set of keypoints in the 2D facial image based on the user-provided keypoint annotations; and updating the coarse facial position map to get a final facial position map so as to reduce the differences between the first set of keypoints and the second set of key points in the 2D facial image. In some embodiments, a final set of keypoints and/or a three-dimensional (3D) facial model of the real-life person is formed from the final facial position map.
