A New Multi-level Error Diffusion Method Based on Fuzzy Inference

We propose a new multi-level error diffusion method that realizes half-toning with high quality. By using fuzzy inference the proposed method decreases dissimilar textures, which are the cause of the low image quality and obtained by a conventional method, around middle quantization levels. In this letter, we apply the proposed method to several digital images. And the simulation results show that the proposed method is superior to the conventional method.
