Patent number: 10785422Abstract: A camera is configured to output a test depth+multi-spectral image including a plurality of pixels. Each pixel corresponds to one of the plurality of sensors of a sensor array of the camera and includes at least a depth value and a spectral value for each spectral light sub-band of a plurality of spectral illuminators of the camera. A face recognition machine is previously trained with a set of labeled training depth+multi-spectral images having a same structure as the test depth+multi-spectral image. The face recognition machine is configured to output a confidence value indicating a likelihood that the test depth+multi-spectral image includes a face.Type: GrantFiled: May 29, 2018Date of Patent: September 22, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Sergio Ortiz Egea, Michael Scott Fenton, Abdelrehim Ahmed

Patent number: 9569005Abstract: A user-centric method and system to identify user-made gestures to control a remote device images the user using a three-dimensional image system, and defines at least one user-centric three-dimensional detection zone dynamically sized appropriately for the user, who is free to move about. Images made within the detection zone are compared to a library of stored gestures, and the thus identified gesture is mapped to an appropriate control command signal coupleable to the remote device. The method and system also provides of a first user to hand off control of the remote device to a second user.Type: GrantFiled: April 3, 2014Date of Patent: February 14, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Abdelrehim Ahmed, Abbas Rafii, Colin Tracy

Patent number: 9361538Abstract: Systems and methods are disclosed for describing and tracking edges within the field of view of one or more imaging devices. In one example, the present system defines a row of pixels taken across a width of the edge, and then determines a binary edge descriptor for the edge by comparing at least one of grayscale values and contrast of pixels within respective pixel pairs from the row of pixels, the result of the comparisons setting bits within the binary descriptor.Type: GrantFiled: December 26, 2012Date of Patent: June 7, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Britta S. Hummel, Oliver Williams, Abdelrehim Ahmed

Publication number: 20140085625Abstract: A system and method are disclosed relating to a pipeline for generating a computer model of a target user, including a hand model of the user's hands and fingers, captured by an image sensor in a NUI system. The computer model represents a best estimate of the position and orientation of a user's hand or hands. The generated hand model may be used by a gaming or other application to determine such things as user gestures and control actions.Type: ApplicationFiled: September 26, 2012Publication date: March 27, 2014Inventors: Abdelrehim Ahmed, Britta Hummel, Travis Perry, Vishali Mogallapu
