Abstract:

This paper presents a new digital halftoning system based on a repulsive potential model, in which black dots correspond to charged particles. Since the charged particles have the charge of the same polarity, they repel each other. By changing the coefficient of the repulsion based on the gray level of the corresponding area of an original continuous-tone image, the distance among black dots is controlled, and halftoning is realized. Because of the repulsion among the black dots, such forces that make the distance between black dots almost uniform come about. Therefore, high quality halftone images with fine texture are produced.
