Patent number: 11380130Abstract: Face authentication can easily be performed based on an input image including a mirror region reflected by a mirror without increasing a storage capacity of a database. With the database, for each face of a person to be authenticated, only one real front image is to be registered as a reference face image. A mirror image processing circuitry detects the mirror region from the input image and to subject a detected mirror region to lateral inversion processing to produce a processed image. A face detection processing circuitry detects a face image from the processed image to generate a detected face image. A face authentication processing circuitry compares the detected face image with the reference face image, to thereby perform face authentication.Type: GrantFiled: September 12, 2018Date of Patent: July 5, 2022Assignee: NEC CORPORATIONInventor: Takayuki Kase

Patent number: 11363251Abstract: Methods, devices and systems are disclosed for improved depth perception in stereoscopic night vision devices. Among these are embodiments for aligning information overlays in the stereo view with associated objects, and for generating stereo information from single lenses or intensifiers. In some illustrative embodiments, a camera and position sensor are provided for at least two viewers, e.g., a pilot and a copilot, such that when a scene overlaps between viewers, the system produces a stereoptic scene, in which the users can more accurately determine a difference in depth between two or more distant objects. An illustrative binocular night vision system uses a high-resolution depth map to present binocular images to a user. In some embodiments, supplementary content can be overlaid, with an appropriate binocular disparity that is based on the depth map.Type: GrantFiled: October 12, 2020Date of Patent: June 14, 2022Assignee: Applied Minds, LLCInventors: Michael Keesling, Clinton Blake Hope, Kevin Robert Keegan, Kjerstin Irja Williams, Bran Ferren, David Foor

Patent number: 11361511Abstract: A method, a mixed reality (MR) system, and a recording medium for detecting a real-world light source in MR are provided. The method is applicable to the MR system having a computing apparatus and a head-mounted display (HMD). In the method, a plurality of light regions of a plurality of continuous images is analyzed, and each of the light regions is projected according to a coordinate position of the HMD corresponding to the plurality of continuous images to generate three-dimensional vectors. Then, the three-dimensional vectors are clustered to predict a directional light in a current image. Finally, a plurality of intersection points between the three-dimensional vectors is calculated, and a point light in the current image is predicted according to the intersection points.Type: GrantFiled: January 16, 2020Date of Patent: June 14, 2022Assignee: HTC CorporationInventor: Yi-Chen Lin
