Abstract :
In this paper, we propose an all-optical approach to the error diffusion algorithm using self electrooptic effect device (SEED) technology. This optical approach combines the advantages of error diffusion coding with optical signal processing technology to extend the resolution of oversampled A/D conversion and the halftone image quality of digital image halftoning beyond that currently possible with existing electronic techniques
