  • Abstract
    The minimal number of real multiplications necessary to compute a length-2m two-dimensional discrete cosine transform is determined. The method of derivation shows that the polynomial transform computation and the Chebyshev transform computation of a 2D DCT have the same multiplicative complexity.
