Patent number: 11748615Abstract: Computer implemented systems are described that implement a differentiable neural architecture search (DNAS) engine executing on one or more processors. The DNAS engine is configured with a stochastic super net defining a layer-wise search space having a plurality of candidate layers, each of the candidate layers specifying one or more operators for a neural network architecture. Further, the DNAS engine is configured to process training data to train weights for the operators in the stochastic super net based on a loss function representing a latency of the respective operator on a target platform, and to select a set of candidate neural network architectures from the trained stochastic super net. The DNAS engine may, for example, be configured to train the stochastic super net by traversing the layer-wise search space using gradient-based optimization of network architecture distribution.Type: GrantFiled: December 5, 2019Date of Patent: September 5, 2023Assignee: META PLATFORMS, INC.Inventors: Bichen Wu, Peizhao Zhang, Peter Vajda, Xiaoliang Dai, Yanghan Wang, Yuandong Tian

Patent number: 11170470Abstract: Techniques are described for content-adaptive downsampling of digital images and videos for computer vision operations, such as semantic segmentation. A computer vision system comprises a memory, one or more processors operably coupled to the memory and a downsampling module configured for execution by the one or more processors to perform, based on a non-uniform sampling model trained to predict content-aware sampling parameters, downsampling input image data to generate downsampled image data. A segmentation module is configured for execution by the one or more processors to perform segmentation on the downsampled image to produce a segmentation result, such as a feature map that assigns pixels of the downsampled image data to object classes. An upsampling module is configured for execution by the one or more processors to perform upsampling according to the segmentation result to produce upsampled image data.Type: GrantFiled: December 6, 2019Date of Patent: November 9, 2021Assignee: Facebook, Inc.Inventors: Zijian He, Peter Vajda, Priyam Chatterjee, Shanghsuan Tsai, Dmitrii Marin

Patent number: 10796452Abstract: In one embodiment, a system accesses a probability model associated with an image depicting a body. The probability model includes probability values associated with regions of the image and each probability value represents a probability of the associated region of the image containing a particular body part. The system selects a subset (e.g., 3) of the probability values based on a comparison of the probability values. For each selected probability value, the system identifies surrounding probability values surrounding the selected probability value and computes a probabilistic maximum based on the selected probability value and the surrounding probability values. Each probabilistic maximum is associated with a location within the regions associated with the selected probability value and the surrounding probability values.Type: GrantFiled: December 31, 2018Date of Patent: October 6, 2020Assignee: Facebook, Inc.Inventors: Peter Vajda, Peizhao Zhang, Matthieu Tony Uyttendaele, Yanghan Wang

Patent number: 10257501Abstract: A canvas generation system generates a canvas view of a scene based on a set of original camera views depicting the scene, for example to recreate a scene in virtual reality. Canvas views can be generated based on a set of synthetic views generated from a set of original camera views. Synthetic views can be generated, for example, by shifting and blending relevant original camera views based on an optical flow across multiple original camera views. An optical flow can be generated using an iterative method which individually optimizes the optical flow vector for each pixel of a camera view and propagates changes in the optical flow to neighboring optical flow vectors.Type: GrantFiled: April 11, 2016Date of Patent: April 9, 2019Assignee: Facebook, Inc.Inventors: Brian Keith Cabral, Forrest Samuel Briggs, Albert Parra Pozo, Peter Vajda
