Abstract

A method and an apparatus for encoding / decoding an image are provided. The method for decoding an image comprises the steps of decoding the block division information about a current block included in a current picture from a bitstream; determining a division method for the current block on the basis of the information; and dividing the current block by using the determined division method, wherein the division method is determined on the basis of whether the current block includes a predetermined boundary.

Description

technical field [0001] The present invention relates to a method and apparatus for encoding / decoding images, and a recording medium storing a bit stream. More particularly, the present invention relates to a method and apparatus for encoding / decoding an image based on a block structure, and a recording medium storing a bitstream. Background technique [0002] Recently, demands for high-resolution and high-quality videos, such as high-definition (HD) and ultra-high-definition (UHD) videos, have increased in various application fields. Since video data has higher resolution and higher quality, the amount of data increases more than existing video data. Therefore, when video data is transmitted using media such as existing wired broadband lines and wireless broadband lines or stored in existing storage media, transmission costs and storage costs increase. In order to solve these problems that arise as the resolution and quality of image data increase, efficient image encoding...
