Abstract
In order to make easily to display, both the digital half toning and the computer generated holography have the binarization process. The error diffusion methods and the optimization techniques (i.e., simulated annealing, genetic algorithm, etc) is commonly utilized to binarization process for both tae digital halftoning and the digital holography. Simulated annealing effective to the optimization of both the point arrangement of the binary image with halftoning and the interference stripes in the computer generated hologram.
