Publication number: 20250071359Abstract: Systems and methods may be used for access control. These systems and methods may include using a data processing system to access a video stream, the video stream including an image including a virtual background, segmenting the image into a foreground portion and a background portion to determine whether the foreground portion or the background portion of the image meets a threshold requirement, and outputting an alert in response to determining that the foreground portion or the background portion of the image fails to meet the threshold requirement.Type: ApplicationFiled: November 7, 2024Publication date: February 27, 2025Inventors: Henrik Valdemar TURBELL, David Yuheng ZHAO, Qingfen LIN

Publication number: 20240212394Abstract: The disclosure herein describes systems and methods for object data storage. In some examples, the method includes generating a profile for an object in a directory, the profile including a first feature vector corresponding to the object and a global unique identifier (GUID) corresponding to the first feature vector in the profile; generating a search scope, the search scope including at least the GUID corresponding to the profile; generating a second feature vector from a live image scan; matching the generated second feature vector from the live image scan to the first feature vector using the generated search scope; identifying the GUID corresponding to the first feature vector that matches the second feature vector; and outputting information corresponding to the object of the profile identified by the GUID corresponding to the first feature vector.Type: ApplicationFiled: March 7, 2024Publication date: June 27, 2024Inventors: William Louis THOMAS, Jinyu LI, Yang CHEN, Youyou HAN OPPENLANDER, Steven John BOWLES, Qingfen LIN

Publication number: 20230308492Abstract: Systems and methods may be used for access control. These systems and methods may include using a data processing system to identify a video stream, determine an identification of a source type of the video stream, determine whether the video stream is live or pre-recorded based on a determined type of the source type, and output an alert to a device in response to determining that the source type indicates the video stream is pre-recorded.Type: ApplicationFiled: August 19, 2021Publication date: September 28, 2023Inventors: Henrik Valdemar TURBELL, David Yuheng ZHAO, Qingfen LIN

Publication number: 20220374636Abstract: In a system including a processor and memory, the memory includes instructions that, when executed by the processor, cause the processor to control the system to perform receiving a video stream capturing objects; identifying, based on the received video stream, object areas corresponding to the objects, respectively; tracking the object areas in the received video stream; generating, based on the tracking of the object areas, visual data sets at a plurality of times, wherein each visual data set is generated at a different time and includes visual data representing each object area; determining a priority of each visual data in each visual data set; selecting, based on the determined priority of each visual data, a group of the visual data to be transmitted to a remote system; and transmitting, to the remote system, the selected group of the visual data.Type: ApplicationFiled: May 24, 2021Publication date: November 24, 2022Applicant: Microsoft Technology Licensing, LLCInventors: Moshe DAVID, Aviv HURVITZ, Eyal KRUPKA, Qingfen LIN, Arash GHANAIE-SICHANIE
