An Investigation on Square Error Rate of Best Matrix Size of Ordered Dither Matrix

Abstract

Up to now, the image quality evaluation method by the visual model whom we are proposing has evaluated it in some binary images. Eight has been assumed to be the best in case of ..preparing.. between in a ordered dither method in the past and binary matrix size n. But the objective evaluation method is not found. The purpose of this paper is objectively to evaluate the best dither matrix size of ordered dither method. Number L of steps compared it according to dither matrix size n to a ordered dither method of 4, 8, and 16. Then, the objective evaluation was done to preparing between in a ordered dither method for number L of steps and matrix size n by the proposed approximation level and the best matrix size was examined. Girl, Moon-surface, and Milk-drop were used for the image.
