Publication number: 20220413602Abstract: A system and a method for performing 2D on-screen user gaze estimation using an input facial image of a user captured using a camera associated to a processing device having a display. The method and system allow automated user calibration through automatic recording of calibration samples each including a calibration facial image of the user and an interaction point corresponding to a point on the display where an occurrence of a user interaction was detected when the corresponding calibration image was captured. The system and method also optimize user-specific parameters using the calibration samples by iteratively minimizing a total difference between the interaction points of a plurality of the calibration samples and corresponding 2D gaze estimation results and convert an estimated 3D gaze direction into a 2D gaze estimation result corresponding to a point on the display, by applying the users-specific parameters.Type: ApplicationFiled: June 23, 2021Publication date: December 29, 2022Inventors: Zhenhao LI, Rasoul MOHAMMADI NASIRI, Zheng LIU, Hisham ELHALABI, Yuanhao YU, Roel VERTEGAAL, Yang WANG, Jin TANG

Publication number: 20220156891Abstract: Methods and systems for image deblurring are described. The weights of a deblurring network are first trained by meta-training the deblurring network on both a primary deblurring task and an auxiliary reconstruction task. Application-time training of the deblurring network is then performed, using an application-time blurry input image, to obtain values of application-time trained weights. Application-time training includes performing the auxiliary reconstruction task on the application-time blurry input image, and updating the weights of the deblurring network based on an auxiliary loss computed from the auxiliary reconstruction task. A deblurred output image is generated from the application-time blurry input image, using the application-time trained weights in the deblurring network.Type: ApplicationFiled: November 16, 2020Publication date: May 19, 2022Inventors: Zhixiang Chi, Yang Wang, Yuanhao Yu, Jin Tang
