  • Abstract
    Shows that the two-dimensional discrete Fourier transform DFT (2 n; 2) can be transformed into a series of distinct second versions of the discrete cosine transform DCT. As a result of the minimal number of real multiplications over the field Q to compute the length 2n second version DCT, the authors derive the minimum number of real multiplications over the field Q necessary to compute a two-dimensional discrete Fourier transform for 2 n×2n real input data
