Two Dimensional Sampling by the Retinal Lattice.

Abstract

A discussion of sampling in two dimensions and its implications for vision is presented. We show that aliasing in two dimensions will change both the apparent frequency and orientation of a grating. Further, we demonstrate that the Nyquist frequency depends on orientation and is higher than the usual estimate of 60 c/deg.
