IMAGE SEGMENTATION METHOD AND APPARATUS FOR IMAGE ENCODING AND DECODING

Title:

IMAGE SEGMENTATION METHOD AND APPARATUS FOR IMAGE ENCODING AND DECODING

Document Type and Number:

WIPO Patent Application WO/2019/216710

Kind Code:

A1

Abstract:

Disclosed is an image decoding method according to one embodiment, comprising the steps of: determining a first encoding block and a second encoding block corresponding to the first encoding block; acquiring a first segmentation type mode and a second segmentation type mode from a bit stream when the size of the first encoding block is less than or equal to a predetermined size; determining the segmentation mode of the first encoding block on the basis of the first segmentation type mode information and determining the segmentation mode of the second encoding block on the basis of the second segmentation type mode information; and decoding a first color component encoding block determined on the basis of the segmentation mode of the first encoding block and a second color component encoding block determined on the basis of the segmentation mode of the second encoding block.
