  • Patent number: 11069135
    Abstract: A method of transferring a facial expression from a subject to a computer generated character that includes receiving a plate with an image of the subject's facial expression, a three-dimensional parameterized deformable model of the subject's face where different facial expressions of the subject can be obtained by varying values of the model parameters, a model of a camera rig used to capture the plate, and a virtual lighting model that estimates lighting conditions when the image on the plate was captured.
    Type: Grant
    Filed: November 12, 2019
    Date of Patent: July 20, 2021
    Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.
    Inventors: Stéphane Grabli, Michael Bao, Per Karefelt, Adam Ferrall-Nunge, Jeffery Yost, Ronald Fedkiw, Cary Phillips, Pablo Helman, Leandro Estebecorena

  • Patent number: 10147219
    Abstract: Performance capture systems and techniques are provided for capturing a performance of a subject and reproducing an animated performance that tracks the subject's performance. For example, systems and techniques are provided for determining control values for controlling an animation model to define features of a computer-generated representation of a subject based on the performance. A method may include obtaining input data corresponding to a pose performed by the subject, the input data including position information defining positions on a face of the subject. The method may further include obtaining an animation model for the subject that includes adjustable controls that control the animation model to define facial features of the computer-generated representation of the face, and matching one or more of the positions on the face with one or more corresponding positions on the animation model.
