摘要： 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.

摘要： 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.
