A separable Hartley-like transform in two or more dimensions
Abstract
This letter introduces a discrete, separable, real-to-real transform, called the cas-cas transform. Theorems for the two-dimensional case are presented, and the cas-cas transform is compared to the Hartley transform as an alternative way to convolve two-dimensional arrays and compute two-dimensional power spectra.
