Abstract

The computer-generated hologram (CGH) is made because of 3D image reconstruction, the pattern recognition and so on. In the synthesis of CGH, quantization causes the adverse effect on image quality. This paper describes the selection of diffusion coefficient about the error diffusion method to reduce a bad influence in quantization. SA is applied to search for diffusion coefficient with the best image quality of the reconstructed image. In this simulation, diffusion coefficient obtained by the search with SA reduces MSE in the reconstructed image to 34% compared with it obtained by a stochastic analysis. The search for diffusion coefficient with SA is effective to obtain the reconstructed image of high image quality.
