IMAGE DECODING METHOD AND DEVICE

WIPO Patent Application WO/2021/194052

A1

Provided are an image decoding method and device. This specification provides an image decoding method comprising the steps of: acquiring a parameter indicating whether a multiple transform set is applicable to a block to be decoded, as well as information about the width of the block to be decoded and the height of the block to be decoded; determining the transform type of the block to be decoded on the basis of at least one of the parameter indicating whether a multiple transform set is applicable, or the information about the width and height of the block to be decoded, and setting a zero-out region of the block to be decoded; and inverse-transforming the block to be decoded on the basis of the zero-out region of the block to be decoded and the result of determining the transform type.
