Patent number: 11856203Abstract: Advances in deep generative models (DGM) have led to the development of neural face video compression codecs that are capable of using an order of magnitude less data than “traditional” engineered codecs. These “neural” codecs can reconstruct a target image by warping a source image to approximate the content of the target image and using a DGM to compensate for imperfections in the warped source image. The determined warping operation may be encoded and transmitted using less data (e.g., transmitting a small number of keypoints, rather than a dense flow field), leading to the bandwidth savings compared to traditional codecs. However, by relying on a single source image only, these methods can lead to inaccurate reconstructions. The techniques presented herein improve image reconstruction quality while maintaining bandwidth savings, via a combination of using multiple source images (i.e., containing multiple views of the first human subject) and novel feature aggregation techniques.Type: GrantFiled: March 22, 2022Date of Patent: December 26, 2023Assignee: Apple Inc.Inventors: Michael Tschannen, Ali Benlalah, Anna Volokitin, Brian Amberg, Sebastian Martin, Stefan Brugger

Patent number: 11068698Abstract: A three-dimensional model (e.g., motion capture model) of a user is generated from captured images or captured video of the user. A machine learning network may track poses and expressions of the user to generate and refine the three-dimensional model. Refinement of the three-dimensional model may provide more accurate tracking of the user's face. Refining of the three-dimensional model may include refining the determinations of poses and expressions at defined locations (e.g., eye corners and/or nose) in the three-dimensional model. The refining may occur in an iterative process. Tracking of the three-dimensional model over time (e.g., during video capture) may be used to generate an animated three-dimensional model (e.g., an animated puppet) of the user that simulates the user's poses and expressions.Type: GrantFiled: September 27, 2019Date of Patent: July 20, 2021Assignee: Apple Inc.Inventors: Sofien Bouaziz, Brian Amberg, Thibaut Weise, Patrick Snape, Stefan Brugger, Alex Mansfield, Reinhard Knothe, Thomas Kiser
