THE METHOD OF DESIGNING STOCHASTIC CLUSTERED-DOT SCREEN BASED ON THE HUMAN VISUAL CHARACTERISTICS AND THE PRINTER MODEL

摘要

Disclose this intensive irregular dot screen design method based on human visual characteristic printer model characteristic. Human visual characteristic and printer model based on the irregular concentration type dot screen design method of characteristic are the location informations for updating initial position message and stage, cluster centers, to determine the initial position by a large amount of point set centers given according to the method for the present invention and preferably include a human visual characteristic and step using printer model, modified characteristics consider that DBS algorithms design a screen to form a scheduled attachment point tightly round center. According to the present invention, when the binary mode design for each gray value, cluster centers are located, because moving object is without a period, cluster centers are that tiltedly, visually thus objectionable mode has the advantages that successively decrease one in the output image.
