Patent number: 10834379Abstract: A wide spread adoption of 3D videos and technologies is hindered by the lack of high-quality 3D content. One promising solution to address this problem is to use automated 2D-to-3D conversion. However, current conversion methods, while general, produce low-quality results with artefacts that are not acceptable to many viewers. Creating a database of 3D stereoscopic videos with accurate depth is, however, very difficult. Computer generated content can be used to generate high-quality 3D video reference database for 2D-to-3D conversion. The method transfers depth information from frames in the 3D reference database to the target frame while respecting object boundaries. It computes depth maps from the depth gradients, and outputs a stereoscopic video.Type: GrantFiled: September 23, 2019Date of Patent: November 10, 2020Inventors: Mohamed M. Hefeeda, Kiana Ali Asghar Calagari, Mohamed Abdelaziz A Mohamed Elgharib, Wojciech Matusik, Piotr Didyk, Alexandre Kaspar

Patent number: 10217187Abstract: The method for dynamic video magnification magnifies small motions occurring simultaneously within large motions. The method involves selecting a region of interest from a video for magnification. The region of interest is warped to obtain a stabilized sequence of frames that discounts large motions. Each frame of the stabilized sequence is decomposed to a foreground layer, a background layer, and an alpha matte layer, and each of the foreground and alpha matte layers is magnified. Then a magnified sequence is generated from the magnified layers using matte inversion. Any image holes in the magnified sequence are filled in using texture synthesis. Finally, the magnified sequence is de-warped to the original space-time coordinates.Type: GrantFiled: June 3, 2016Date of Patent: February 26, 2019Assignees: QATAR FOUNDATION FOR EDUCATION, SCIENCE AND IMMUNITY DEVELOPMENT, MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Mohamed Abdelaziz A.

Patent number: 10152048Abstract: A control system includes first and second hardware components and a server which is remote from the hardware components. The server is a server in the cloud which is connected via the Internet to the hardware components. A control module is implemented as a service running on the server and the control module is operable to communicate with the hardware components to control at least one of the hardware components.Type: GrantFiled: April 26, 2013Date of Patent: December 11, 2018Assignee: Qatar FoundationInventors: Mohamed M. Hefeeda, Tamir A. Hegazy

Patent number: 8509600Abstract: A method for detecting whether query video data appears in a reference video, comprising determining a measure of depth from a portion of the query video data, comparing the measure against a measure of depth for the reference video to perform a depth match and, if a match is determined; comparing a visual signature derived from the query video data against a visual signature of the reference video to perform a visual match to determine a measure representing the likelihood that the query video data derives from the reference video.Type: GrantFiled: August 3, 2011Date of Patent: August 13, 2013Assignee: Qatar FoundationInventors: Mohamed M. Hefeeda, Nagmeh F. Khodabakhshi
