Patent number: 11954904Abstract: Disclosed are methods, apparatus and systems for real-time gesture recognition. One exemplary method for the real-time identification of a gesture communicated by a subject includes receiving, by a first thread of the one or more multi-threaded processors, a first set of image frames associated with the gesture, the first set of image frames captured during a first time interval, performing, by the first thread, pose estimation on each frame of the first set of image frames including eliminating background information from each frame to obtain one or more areas of interest, storing information representative of the one or more areas of interest in a shared memory accessible to the one or more multi-threaded processors, and performing, by a second thread of the one or more multi-threaded processors, a gesture recognition operation on a second set of image frames associated with the gesture.Type: GrantFiled: July 6, 2021Date of Patent: April 9, 2024Assignee: AVODAH, INC.Inventors: Trevor Chandler, Dallas Nash, Michael Menefee

Patent number: 11928592Abstract: Methods, devices and systems for training a pattern recognition system are described. In one example, a method for training a sign language translation system includes generating a three-dimensional (3D) scene that includes a 3D model simulating a gesture that represents a letter, a word, or a phrase in a sign language. The method includes obtaining a value indicative of a total number of training images to be generated, using the value indicative of the total number of training images to determine a plurality of variations of the 3D scene for generating of the training images, applying each of plurality of variations to the 3D scene to produce a plurality of modified 3D scenes, and capturing an image of each of the plurality of modified 3D scenes to form the training images for a neural network of the sign language translation system.Type: GrantFiled: June 14, 2021Date of Patent: March 12, 2024Assignee: Avodah, Inc.Inventors: Trevor Chandler, Dallas Nash, Michael Menefee

Publication number: 20230377376Abstract: Methods, apparatus and systems for recognizing sign language movements using multiple input and output modalities. One example method includes capturing a movement associated with the sign language using a set of visual sensing devices, the set of visual sensing devices comprising multiple apertures oriented with respect to the subject to receive optical signals corresponding to the movement from multiple angles, generating digital information corresponding to the movement based on the optical signals from the multiple angles, collecting depth information corresponding to the movement in one or more planes perpendicular to an image plane captured by the set of visual sensing devices, producing a reduced set of digital information by removing at least some of the digital information based on the depth information, generating a composite digital representation by aligning at least a portion of the reduced set of digital information, and recognizing the movement based on the composite digital representation.Type: ApplicationFiled: January 17, 2023Publication date: November 23, 2023Inventors: Michael Menefee, Dallas Nash, Trevor Chandler

Publication number: 20230325609Abstract: Disclosed are methods, devices and systems for translating a document using neural networks and leveraging the hierarchical structure of the document. Embodiments of the disclosed technology use bi-level structures that incorporate both the unique meanings of words and unique grammatical rules on matching grammatical word types in a document to train a neural network. The trained neural network is used to translate documents in an automated and efficient manner. The disclosed embodiments advantageously use manual (or human) analysis on a small portion of text to identify the unique means and grammatical rules, which is then leveraged to translate a much larger corpus of text with increased reliability and accuracy.Type: ApplicationFiled: April 6, 2023Publication date: October 12, 2023Inventors: Trevor Chandler, Dallas Nash
