Original Abstract Submitted

Provided is an image decoding method including: obtaining, from a bitstream, a syntax element regarding multiple transform selection (MTS) with respect to a current coding unit or a current transform unit included in the current coding unit; determining a horizontal transform kernel or a vertical transform kernel with respect to the current transform unit based on the obtained syntax element; obtaining a residual signal by performing inverse transformation on the current transform unit, based on the determined horizontal transform kernel or vertical transform kernel with respect to the current transform unit; and generating a reconstruction block including the current coding unit or the current transform unit based on the residual signal with respect to the current transform unit.
