Title:
METHOD AND APPARATUS FOR DECODING VIDEO ACCORDING TO AFFINE PREDICTION IN VIDEO CODING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/226066
Kind Code:
A1
Abstract:
A method for decoding a video performed by a decoding apparatus according to the present invention comprises the steps of: deriving neighboring blocks of a current block and a scan order; deriving at least one affine merge candidate block by scanning the neighboring blocks in the scan order; deriving motion vectors of control points (CPs) for the current block on the basis of the motion vectors of the CPs for the affine merge candidate block; deriving a motion vector of a sub-block or sample unit in the current block on the basis of the motion vectors of the CPs; deriving a prediction sample for the current block on the basis of the motion vector of the sub-block or the sample unit; and generating a reconstructed sample on the basis of the prediction sample.
