Abstract

A probabilistic model is introduced to describe error diffusion (a method of binarization). This model is solved for general error-diffusion coefficients. The solution leads to an analytic error expression that is minimized to optimize the quality of binarization. It is shown that this procedure is useful in the production of computer-generated holograms. Simulations are presented to verify both the theoretical development and the optimization procedure.
