In this paper, a new error diffusion method is proposed that provides high quality ED results. The goal of half-toning method is to quantize each pixel to one bit binary pixel. The proposed error diffusion method is based on half toning method, which is known as Floyd and Steinberg’s filter. To expedite processing time, the denominator of the proposed method is chosen in 2k form, where k is integer number. Therefore, the method is faster than the previous methods, while preserving simplicity. Experimental results show that the obtained red, green, blue channels and color images look satisfactory for viewer.
