Optimization of error diffusion for 3-D image reconstruction using GA

Abstract

Computer-generated hologram (CGH) is made for three dimensional image reconstruction of a virtual object. Error diffusion method is used to improve the reconstructed image. The selection of diffusion coefficient exerts an influence to the image quality of the reconstructed image. In this article, diffusion coefficient is optimized by using genetic algorithm (GA). Diffusion coefficient searched by GA is able to decrease the mean square error of the reconstructed image by 10% compared with it searched by the stochastic method.
