Title:
変換に基づく映像コーディング方法及びその装置
Document Type and Number:
Japanese Patent JP7418561
Kind Code:
B2
Abstract:
An image decoding method according to the present document can comprise the steps of: deriving a transform coefficient for a current block on the basis of residual information; determining whether an effective coefficient is in a second area that excludes the upper left first area of the current block; parsing an MTS index from a bitstream if the effective coefficient is not in the second area; and deriving a residual sample by applying, to transform coefficients of the first area, an MTS kernel derived on the basis of the MTS index.
