An efficient algorithm for determining the sequency vector S?<inf>n</inf>of a 2<sup>n</sup>? 2<sup>n</sup>Hadamard matrix is developed. The method requires fewer computation steps than a previously known method.
Walsh functions, Hadamard functions, image processing, orthogonal transforms, sequency (ordering)
