Title:
SYSTEM AND METHOD FOR MOTION WARPING USING MULTI-EXPOSURE FRAMES
Document Type and Number:
WIPO Patent Application WO/2021/201438
Kind Code:
A1
Abstract:
Provided is a method comprising obtaining, a first image frame and multiple second image frames of a scene, each of the plurality of second image frames having an exposure time different from an exposure time of the first image frame, generating optical flow information using at least one convolutional neural network, wherein the optical flow information indicates motion information of at least one object in the scene, determining at least one parameter for motion correction process based on the optical flow information, performing the motion correction process on at least one of the first image frame and the plurality of second image frames to generate a first intermediate data, wherein the motion correction process uses the identified at least one parameters, and generating a target image frame from the first intermediate data.
