Title:
METHOD AND DEVICE FOR INTER-PREDICTION MODE-BASED IMAGE PROCESSING
Document Type and Number:
WIPO Patent Application WO/2019/027145
Kind Code:
A1
Abstract:
Disclosed is a method and a device for inter-prediction mode-based image processing. Specifically, a method for processing an image on the basis of inter-prediction may comprise the steps of: identifying whether an affine encoding block encoded in an affine mode exists among neighboring blocks of a current block, wherein the affine mode indicates a mode for deriving a motion vector in units of pixels or units of sub-blocks by using a motion vector of a control point; and as a result of the identification, when the affine encoding block exists among the neighboring blocks, deriving a first motion vector candidate of the control point of the current block, on the basis of motion information of the affine encoding block.
