Abstract :
A unified structure for performing fast discrete orthogonal transformations like Fourier, Walsh, Haar, cosine and sine ones and nonlinear operations like scanning window data sorting for order statistic and L-filters is proposed and described. It permits one to implement a wide class of techniques used in signal and image processing applications
