Abstract
A method for decoding an image according to the present invention comprises the steps of: determining whether a second inverse transform is applied to a coding block including a plurality of sub-blocks; and applying the second inverse transform to at least one of the plurality of sub-blocks when it is determined that the second inverse transform is applied to the coding block. In this case, whether the second inverse transform is applied to the coding block may be determined by comparing the size of one of the plurality of sub-blocks with a threshold value.
