Document Type and Number:
WIPO Patent Application WO/2021/004038
Kind Code:
A1
Abstract:
A method for video stabilization may include obtaining a target frame of a video; dividing a plurality of pixels of the target frame into a plurality of pixel groups; determining a plurality of first feature points in the target frame; determining first location information of the plurality of first feature points in the target frame; determining second location information of the plurality of first feature points in a frame prior to the target frame in the video; obtaining a global homography matrix; determining an offset of each of the plurality of first feature points; determining a fitting result based on the first location information and the offsets; for each of the plurality of pixel groups, determining a correction matrix; and for each of the plurality of pixel groups, processing the pixels in the pixel group based on the global homography matrix and the correction matrix.
