Title:
IMAGE PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/181507
Kind Code:
A1
Abstract:
Provided are an image processing method and apparatus. The method comprises: obtaining a control point motion vector (CPMV) of an image block; and obtaining MVs of sub-image blocks in the image block according to the CPMV thereof, the MV being the whole pixel accuracy. By using the MVs of the sub-image blocks used as image processing units as the whole pixel accuracy, a motion compensation process of the sub-image blocks is allowed not to involve sub-pixels, thereby reducing the bandwidth pressure generated by an Affine prediction technology to a certain extent.
