Abstract
A method for encoding video or images includes receiving input data associated with a block within a video or image frame and performing a transform of the input data to produce a first set of output coefficients. The method also includes receiving the first set of output coefficients and performing a second transform to produce a second set of output coefficients. The method further includes quantizing the second set of output coefficients. The second transform is performed using a rotational transform matrix that is selected to maximize a degree of orthogonality of the rotational transform matrix.
