In this paper we propose a modified evaluation method to improve the performance of an image halftoning technique using GAs. We design the algorithm to avoid noise in the fitness function by evolving all image blocks concurrently, exploiting the inter-block correlation, and sharing information between neighbor image blocks. The effectiveness of the method when the population and image block size are reduced, and the configuration of selection and genetic operators are investigated in detail. Simulation results show that the proposed method can remarkably reduce the entire processing time to generate high quality bi-level halftone images. © Springer-Verlag Berlin Heidelberg 2003.
