  • Patent number: 10019826
    Abstract: A method of transferring a facial expression from a subject to a computer-generated character and a system and non-transitory computer-readable medium for the same. The method can include receiving an input image depicting a face of a subject; matching a first facial model to the input image; generating a displacement map representing of finer-scale details not present in the first facial model using a regression function that estimates the shape of the finer-scale details. The displacement map can be combined with the first facial model to create a second facial model that includes the finer-scale details, and the second facial model can be rendered, if desired, to create a computer-generated image of the face of the subject that includes the finer-scale details.

  • Publication number: 20180130245
    Abstract: Methods, systems, and computer-readable memory are provided for determining time-varying anatomical and physiological tissue characteristics of an animation rig. For example, shape and material properties are defined for a plurality of sample configurations of the animation rig. The shape and material properties are associated with the plurality of sample configurations. An animation of the animation rig is obtained, and one or more configurations of the animation rig are determined for one or more frames of the animation. The determined one or more configurations include shape and material properties, and are determined using one or more sample configurations of the animation rig. A simulation of the animation rig is performed using the determined one or more configurations. Performing the simulation includes computing physical effects for addition to the animation of the animation rig.

  • Publication number: 20180085201
    Abstract: A system and method for non-invasive reconstruction of an entire object-specific or person-specific teeth row from just a set of photographs of the mouth region of an object (e.g., an animal) or a person (e.g., an actor or a patient) are provided. A teeth statistic model defining individual teeth in a teeth row can be developed. The teeth statistical model can jointly describe shape and pose variations per tooth, and as well as placement of the individual teeth in the teeth row. In some embodiments, the teeth statistic model can be trained using teeth information from 3D scan data of different sample subjects. The 3D scan data can be used to establish a database of teeth of various shapes and poses. Geometry information regarding the individual teeth can be extracted from the 3D scan data. The teeth statistic model can be trained using the geometry information regarding the individual teeth.

    Abstract: A process, computer program product, and apparatus provide color and shape stylization for a captured hairstyle. The process, computer program product, and apparatus receive a plurality of images of a hairstyle in an n dimensional space at a plurality of different angles. Further, the process, computer program product, and apparatus generate a mesh surface in an n?1 dimensional space. In addition, the process, computer program product, and apparatus combine color data from the plurality of images at the plurality of different angles with mesh geometry data of the mesh surface. The process, computer program product, and apparatus also stylize the color data with an n dimensional filter that projects the color data to the n?1 dimensional space of the mesh surface. The process, computer program product, and apparatus may also stylize the geometric shape details in a coherent manner with the color.

  • Patent number: 9652890
    Abstract: Techniques and systems are described for generating an anatomically-constrained local model and for performing performance capture using the model. The local model includes a local shape subspace and an anatomical subspace. In one example, the local shape subspace constrains local deformation of various patches that represent the geometry of a subject's face. In the same example, the anatomical subspace includes an anatomical bone structure, and can be used to constrain movement and deformation of the patches globally on the subject's face. The anatomically-constrained local face model and performance capture technique can be used to track three-dimensional faces or other parts of a subject from motion data in a high-quality manner. Local model parameters that best describe the observed motion of the subject's physical deformations (e.g., facial expressions) under the given constraints are estimated through optimization.
