Abstract

The present invention relates to a video signal processing method and device for increasing prediction accuracy and improving encoding efficiency by using a simplified affine motion model. The video signal processing method according to the present invention induces an affine motion vector by using a plurality of motion vectors related to a current block and performs motion compensation on the basis of the affine motion vector and a location of a current sample.

Description

technical field [0001] The present invention relates to methods and devices for processing video signals. Background technique [0002] Recently, demands for high-resolution and high-quality images (for example, high-definition (HD) images and ultra-high-definition (UHD) images) have increased in various application fields. However, the data amount of image data of higher resolution and quality increases compared with conventional image data. Therefore, when image data is transferred by using a medium such as conventional wired and wireless broadband networks, or when image data is stored by using a conventional storage medium, the cost of transmission and storage increases. In order to solve these problems that arise as the resolution and quality of image data increase, efficient image encoding / decoding techniques can be utilized. [0003] Image compression techniques include various techniques, including: an inter-frame prediction technique that predicts pixel values ​​i...
