Abstract

The invention discloses a method for dividing an image. The method comprises following steps: determining whether to divide a first coding block into a plurality of second coding blocks by tree-basedblock division; based on the result, dividing the first coding block into a plurality of second coding blocks, wherein the tree-based block division includes at least one of binary tree division or ternary tree division, the binary tree division represents a division type of dividing the first coding block into two second coding blocks, and the ternary tree division represents a division type of dividing the first coding block into three second coding blocks.

Description

[0001] This application is a divisional application of an application whose national application number is 201780073662.3, the international filing date is October 10, 2017, the country entry date is May 28, 2019, and the invention title is "Image data encoding / decoding method and device" .
