Original Abstract Submitted
An apparatus includes at least one processor; and at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: determine a horizontal dimension of a transform block corresponding to a horizontal direction of the transform block and a vertical dimension of the transform block corresponding to a vertical direction of the transform block; determine a first transform and a second transform, wherein the first transform has smaller first coefficient for its first basis function compared to a first coefficient of a first basis function of the second transform; select the first transform having smaller first coefficient for its first basis function for the direction with the smaller dimension of the transform block and select the second transform having larger first coefficient for its first basis function for the direction with the larger dimension of the transform block.
