Paper Abstract

In a previous paper, we proposed a multi-level error diffusion method for improvement of image quality in digital halftoning. Those obtained images were evaluated by using the quantization levels. However, this quality criterion was not good parameters for evaluation of images. In this paper, RMS (Root Mean Square) granularity and SNR (Signal to Noise Ratio) were introduced to evaluate the multi-level error diffusion images recorded by color printers with the resolution of 200 DPI and 400 DPI. RMS granularity and SNR of eleven images with different quantization levels produced by the method were calculated. The results shows that both physical values are well correlated to the observer rating values.
