Abstract :
A geometrical transformation changes the locations of image pixels in arbitrary ways. Such permutations of locations are useful for highly parallel communications systems. We discuss the usefulness of several specific geometrical transformation setups. Important aspects are the use of macro- or micro-optical hardware, and also distinction between SIMD and MIMD type of permutations
