Abstract
A method for decoding an image according to the present invention comprises the steps of: partitioning a coding block into a plurality of sub-blocks in a horizontal direction or vertical direction; determining whether a second inverse transform is applied to the coding block; and when it is determined that the second inverse transform is applied to the coding block, applying the second inverse transform to at least one of the plurality of sub-blocks.
