ResumoA generalisation of the error diffusion algorithm is obtained by considering a filter for binarisation errors in the reconstruction plane as an error diffusion mask in the hologram plane. The method of projection onto convex sets is used to determine an optimum filter function. Simulated and experimental results are presented. The new method gives superior results over the original error diffusion algorithm.
