Patent number: 9317954Abstract: Techniques for facial performance capture using an adaptive model are provided herein. For example, a computer-implemented method may include obtaining a three-dimensional scan of a subject and a generating customized digital model including a set of blendshapes using the three-dimensional scan, each of one or more blendshapes of the set of blendshapes representing at least a portion of a characteristic of the subject. The method may further include receiving input data of the subject, the input data including video data and depth data, tracking body deformations of the subject by fitting the input data using one or more of the blendshapes of the set, and fitting a refined linear model onto the input data using one or more adaptive principal component analysis shapes.Type: GrantFiled: December 26, 2013Date of Patent: April 19, 2016Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.Inventors: Hao Li, Jihun Yu, Yuting Ye, Christoph Bregler

Patent number: 9002064Abstract: A computer program product tangibly embodied in a computer-readable storage medium includes instructions that when executed by a processor perform a method. The method includes identifying a frame of a video sequence, transforming a model into an initial guess for how the region appears in the frame, performing an exhaustive search of the frame, performing a plurality of optimization procedures, wherein at least one additional model parameter is taken into account as each subsequent optimization procedure is initiated. A system includes a computer readable storage medium, a graphical user interface, an input device, a model for texture and shape of the region, the model generated using the video sequence and stored in the computer readable storage medium, and a solver component.Type: GrantFiled: November 4, 2013Date of Patent: April 7, 2015Assignee: Lucasfilm Entertainment Company Ltd.Inventors: Christoph Bregler, Kiran S. Bhat, Brett A. Allen

Publication number: 20060192852Abstract: A system, method, software arrangement and computer-accessible medium are provided for tracking moveable objects, such as large balls, that a group of participants can interact with. For example, the motion of the objects may be used to control or influence the motion of certain virtual objects generated in a virtual environment, which may interact with other virtual objects. The virtual objects and their interactions may be used to generate video information, which can be displayed to the participants and which may indicate the occurrence of certain game-related events. Audio information may also be generated based on the interactions, and used to produce sounds separately from or in conjunction with the virtual objects.Type: ApplicationFiled: February 9, 2006Publication date: August 31, 2006Inventors: Sally Rosenthal, Christoph Bregler, Clothilde Castiglia, Jessica De Vincenzo, Roger Dubois, Kevin Feeley, Tom Igoe, Jonathan Meyer, Michael Naimark, Alexandru Postelnicu, Michael Rabinovich, Katie Salen, Jeremi Sudol, Bo Wright

Patent number: 6188776Abstract: The identification of hidden data, such as feature-based control points in an image, from a set of observable data, such as the image, is achieved through a two-stage approach. The first stage involves a learning process, in which a number of sample data sets, e.g. images, are analyzed to identify the correspondence between observable data, such as visual aspects of the image, and the desired hidden data, such as the control points. Two models are created. A feature appearance-only model is created from aligned examples of the feature in the observed data. In addition, each labeled data set is processed to generate a coupled model of the aligned observed data and the associated hidden data. In the image processing embodiment, these two models might be affine manifold models of an object's appearance and of the coupling between that appearance and a set of locations on the object's surface.Type: GrantFiled: May 21, 1996Date of Patent: February 13, 2001Assignee: Interval Research CorporationInventors: Michele Covell, Christoph Bregler

Patent number: 5880788Abstract: The synchronization of an existing video to a new soundtrack is carried out through the phonetic analysis of the original soundtrack and the new soundtrack. Individual speech sounds, such as phones, are identified in the soundtrack for the original video recording, and the images corresponding thereto are stored. The new soundtrack is similarly analyzed to identify individual speech sounds, which are used to select the stored images and create a new video sequence. The sequence of images are then smoothly fitted to one another, to provide a video stream that is synchronized to the new soundtrack. This approach permits a given video sequence to be synchronized to any arbitrary utterance. Furthermore, the matching of the video images to the new speech sounds can be carried out in a highly automated manner, thereby reducing required manual effort.Type: GrantFiled: March 25, 1996Date of Patent: March 9, 1999Assignee: Interval Research CorporationInventor: Christoph Bregler
