The Regularized Fast Hartley Transform - Low-Complexity Parallel Computation of the FHT in One and Multiple Dimensions

This book describes how a key signal/image processing algorithm – that of the fast Hartley transform (FHT) or, via a simple conversion routine between their outputs, of the real-data version of the ubiquitous fast Fourier transform (FFT) – might best be formulated to facilitate computationally-efficient solutions.
