Algebraic signal processing theory: Cooley–Tukey type algorithms on the 2-D hexagonal spatial lattice

Recently, we introduced the framework for signal processing on a nonseparable 2-D hexagonal spatial lattice including the associated notion of Fourier transform called discrete triangle transform (DTT). Spatial means that the lattice is undirected in contrast to earlier work by Mersereau introducing...
