METHOD, APPARATUS AND SYSTEM FOR ADAPTATING A MACHINE LEARNING MODEL FOR OPTICAL FLOW MAP PREDICTION
Publication number: 20230148384Abstract: There is provided a method, apparatus and system for adapting a machine learning model for optical flow prediction. A machine learning model can be trained or adapted based on compressed video data, using motion vector information extracted from the compressed video data as ground-truth information for use in adapting the model to a motion vector prediction task. The model so adapted can accordingly be adapted for the similar task of optical flow prediction. Thus, the model can be adapted at test time to image data which is taken from an appropriate distribution. A meta-learning process can be performed prior to such model adaptation to potentially improve the model's performance.Type: ApplicationFiled: November 11, 2021Publication date: May 11, 2023Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Wentao LIU, Seyed Mehdi AYYOUBZADEH, Yuanhao YU, Irina KEZELE, Yang WANG, Xiaolin WU, Jin TANG -
Patent number: 11630510Abstract: 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.

Publication number: 20230057261Abstract: A method, device and computer-readable medium for generating a super-resolution version of a compressed video stream. By leveraging the motion information and residual information in compressed video streams, described examples are able to skip the time-consuming motion-estimation step for most frames and make the most use of the SR results of key frames. A key frame SR module generates SR versions of I-frames and other key frames of a compressed video stream using techniques similar to existing multi-frame approaches to VSR. A non-key frame SR module generates SR version of the non-key inter frames between these key frames by making use of motion information and residual information used to encode the inter frames in the compressed video stream.Type: ApplicationFiled: August 19, 2021Publication date: February 23, 2023Inventors: Wentao LIU, Yuanhao YU, Yang WANG, Juwei LU, Xiaolin WU, Jin TANG
