We formulate the error diffusion processing as the optimization problem and propose an error diffusion halftoning method. The method consists of a cross bilateral filter with an iterative procedure and preserves both smoothness and edge sharpness in an original gray scale image. Experimental results show the proposed method achieves better performance than the standard error diffusion method.
