Patent number: 11535154Abstract: A method for calibrating a vehicular vision system includes disposing a camera at a vehicle, disposing a processor at the vehicle, and disposing a video display screen in the vehicle so as to be viewable by the vehicle driver. The video display screen is operable to display video images derived from image data captured by the imager of the camera. Image data is captured by the imager of the camera and provided to the processor. The video display screen displays video images derived from image data captured by the imager of the camera. The processor generates a graphic overlay for display with the video images at the video display screen. Responsive to processing captured image data, the vehicular vision system is calibrated by adapting an orientation and position of the image data relative to the generated graphic overlay to a corrected orientation and position relative to the generated graphic overlay.Type: GrantFiled: March 10, 2021Date of Patent: December 27, 2022Assignee: MAGNA ELECTRONICS INC.Inventor: Benjamin May

Patent number: 11538264Abstract: A document scanner includes an enclosure with a scanning area. A transparent platform in the scanning area allows a user to position a document for authentication. A top camera takes a picture of the top of the document and a bottom camera takes a picture of the bottom under multiple light conditions including UV, IR, and white light. Mirrors reduce the enclosure size and multiple computers within the enclosure share work to process image data and determine document type. Types are searched in order based historically detected types. Barcode data is decoded and image samples are filtered as one of the computers finds a match. Security features are checked for the detected type and fake variants of the detected type are checked. Card information and formatting is validated and face data captured from a face camera and as shown on the document are matched against a database of banned users.Type: GrantFiled: June 25, 2020Date of Patent: December 27, 2022Assignee: Servall Data Systems Inc.Inventors: Alberio Bathory-Frota, James Marusiak, Joel Gallant

Patent number: 11470299Abstract: A method and system for encoding a stereoscopic image pair is disclosed. Groups of pixels are analyzed to determine the depth of each pixel group. The number of bits per pixel used to encode each pixel group is selected based on the depth of that pixel group. Therefore, images of objects closer to the camera pair, which appear closer to the viewer, are encoded with a larger number of bits per pixel than objects perceived to be farther from the viewer. The number of bits per pixel may also be increased based on a number of objects depicted or motion detected. The size of prediction blocks used to encode image portions may also be determined based on an angular distance of an image portion relative to the center of the frame. Therefore, smaller prediction blocks may be used to encode image portions closer to the center of the frame.Type: GrantFiled: September 25, 2020Date of Patent: October 11, 2022Assignee: Nevermind Capital LLCInventors: Ramesh Panchagnula, Alan Moss

Patent number: 11451798Abstract: A system for providing improved video quality and compression efficiency during encoding by detecting video segments having film grain approaching the “Red Lady” problem. The system detects when film grain approaches the level of the “Red Lady” problem by measuring frame-by-frame temporal differences (ME scores). From the ME scores, two key indicators are identified: (1) The average temporal difference in frames with an intermediate motion level higher than frames of non-noisy video; and (2) The fluctuation of the temporal differences between frames in a group is very small. When these indicators identify a high film video, a signal is provided to an encoder which allocates less bits to I frames and more bits to P and B frames than for other frames of video without comparable film grain.Type: GrantFiled: December 8, 2015Date of Patent: September 20, 2022Assignee: ARRIS Enterprises LLCInventors: Wei Zhou, Jane Perera, Wayne D.
