Patent number: 11276231Abstract: Techniques are disclosed for training and applying nonlinear face models. In embodiments, a nonlinear face model includes an identity encoder, an expression encoder, and a decoder. The identity encoder takes as input a representation of a facial identity, such as a neutral face mesh minus a reference mesh, and outputs a code associated with the facial identity. The expression encoder takes as input a representation of a target expression, such as a set of blendweight values, and outputs a code associated with the target expression. The codes associated with the facial identity and the facial expression can be concatenated and input into the decoder, which outputs a representation of a face having the facial identity and expression. The representation of the face can include vertex displacements for deforming the reference mesh.Type: GrantFiled: March 4, 2020Date of Patent: March 15, 2022Assignees: DISNEY ENTERPRISES, INC., ETH ZÜRICH, (EIDGENÖSSISCHE TECHNISCHE HOCHSCHULE ZÜRICH)Inventors: Prashanth Chandran, Dominik Thabo Beeler, Derek Edward Bradley

Patent number: 11257276Abstract: Techniques are disclosed for generating digital faces. In some examples, a style-based generator receives as inputs initial tensor(s) and style vector(s) corresponding to user-selected semantic attribute styles, such as the desired expression, gender, age, identity, and/or ethnicity of a digital face. The style-based generator is trained to process such inputs and output low-resolution appearance map(s) for the digital face, such as a texture map, a normal map, and/or a specular roughness map. The low-resolution appearance map(s) are further processed using a super-resolution generator that is trained to take the low-resolution appearance map(s) and low-resolution 3D geometry of the digital face as inputs and output high-resolution appearance map(s) that align with high-resolution 3D geometry of the digital face. Such high-resolution appearance map(s) and high-resolution 3D geometry can then be used to render standalone images or the frames of a video that include the digital face.Type: GrantFiled: June 8, 2020Date of Patent: February 22, 2022Assignees: DISNEY ENTERPRISES, INC., ETH ZURICH, (EIDGENÖSSISCHE TECHNISCHE HOCHSCHULE ZÜRICH)Inventors: Prashanth Chandran, Dominik Thabo Beeler, Derek Edward Bradley

Patent number: 11222466Abstract: Techniques are disclosed for changing the identities of faces in video frames and images. In embodiments, three-dimensional (3D) geometry of a face is used to inform the facial identity change produced by an image-to-image translation model, such as a comb network model. In some embodiments, the model can take a two-dimensional (2D) texture map and/or a 3D displacement map associated with one facial identity as inputs and output another 2D texture map and/or 3D displacement map associated with a different facial identity. The other 2D texture map and/or 3D displacement map can then be used to render an image that includes the different facial identity.Type: GrantFiled: September 30, 2020Date of Patent: January 11, 2022Assignees: Disney Enterprises, Inc., ETH Zürich (Eidgenössische Technische Hochschule Zürich)Inventors: Jacek Krzysztof Naruniec, Derek Edward Bradley, Thomas Etterlin, Paulo Fabiano Urnau Gotardo, Leonhard Markus Helminger, Christopher Richard Schroers, Romann Matthew Weber

Publication number: 20220005268Abstract: Techniques are disclosed for creating digital faces. In some examples, an anatomical face model is generated from a data set including captured facial geometries of different individuals and associated bone geometries. A model generator segments each of the captured facial geometries into patches, compresses the segmented geometry associated with each patch to determine local deformation subspaces of the anatomical face model, and determines corresponding compressed anatomical subspaces of the anatomical face model. A sculpting application determines, based on sculpting input from a user, constraints for an optimization to determine parameter values associated with the anatomical face model. The parameter values can be used, along with the anatomical face model, to generate facial geometry that reflects the sculpting input.Type: ApplicationFiled: July 6, 2020Publication date: January 6, 2022Inventors: Aurel GRUBER, Marco FRATARCANGELI, Derek Edward BRADLEY, Gaspard ZOSS, Dominik Thabo BEELER

Publication number: 20220004741Abstract: Techniques are disclosed for capturing facial appearance properties. In some examples, a facial capture system includes light source(s) that produce linearly polarized light, at least one camera that is cross-polarized with respect to the polarization of light produced by the light source(s), and at least one other camera that is not cross-polarized with respect to the polarization of the light produced by the light source(s).

Patent number: 11170550Abstract: A retargeting engine automatically performs a retargeting operation. The retargeting engine generates an anatomical local model of a digital character based on performance capture data and/or a 3D model of the digital character. The anatomical local model includes an anatomical model corresponding to internal features of the digital character and a local model corresponding to external features of the digital character. The retargeting engine includes a Machine Learning model that maps a set of locations associated with the face of a performer to a corresponding set of locations associated with the face of the digital character. The retargeting engine includes a solver that modifies a set of parameters associated with the anatomical local model to cause the digital character to exhibit one or more facial expressions enacted by the performer, thereby retargeting those facial expressions onto the digital character.Type: GrantFiled: November 26, 2019Date of Patent: November 9, 2021Assignee: Disney Enterprises, Inc.Inventors: Derek Edward Bradley, Dominik Thabo Beeler

Patent number: 11151767Abstract: A removal model is trained to predict secondary dynamics associated with an individual enacting a performance. For a given sequence of frames that includes an individual enacting a performance and secondary dynamics, a retargeting application identifies a set of rigid points that correspond to skeletal regions of the individual and a set of non-rigid points that correspond to non-skeletal region of the individual. For each frame in the sequence of frames, the application applies the removal model that takes as inputs a velocity history of a non-rigid point and a velocity history of the rigid points in a temporal window around the frame, and outputs a delta vector for the non-rigid point indicating a displacement for reducing secondary dynamics in the frame. In addition, a trained synthesis model can be applied to determine a delta vector for every non-rigid point indicating displacements for adding new secondary dynamics.Type: GrantFiled: July 2, 2020Date of Patent: October 19, 2021Assignee: Disney Enterprises, Inc.Inventors: Gaspard Zoss, Eftychios Sifakis, Dominik Thabo Beeler, Derek Edward Bradley

Publication number: 20210166458Abstract: A modeling engine generates a prediction model that quantifies and predicts secondary dynamics associated with the face of a performer enacting a performance. The modeling engine generates a set of geometric representations that represents the face of the performer enacting different facial expressions under a range of loading conditions. For a given facial expression and specific loading condition, the modeling engine trains a Machine Learning model to predict how soft tissue regions of the face of the performer change in response to external forces applied to the performer during the performance. The modeling engine combines different expression models associated with different facial expressions to generate a prediction model. The prediction model can be used to predict and remove secondary dynamics from a given geometric representation of a performance or to generate and add secondary dynamics to a given geometric representation of a performance.Type: ApplicationFiled: December 3, 2019Publication date: June 3, 2021Inventors: Dominik Thabo BEELER, Derek Edward BRADLEY, Eftychios Dimitrios Sifakis, Gaspard Zoss
