Abstract
This paper presents a method of dithering which attempts to exploit the inevitable textures generated by all dithering schemes. We concentrate on rendering continuous tone (monochrome or color) images on a CRT display with a small number (on the order of 16 - 256) of distinct colors. Monochrome (especially bi-level) dithering techniques are well studied. We have previously demonstrated that texture introduced by the dithering process can significantly affect the appearance of the image. We then developed a scheme by which the user had some control over these texture effects and could then choose (locally) different ordered-dither matrices based on measured properties of the original image (e.g., the local gradient). In this paper, we exploit texture as an alternate channel of information. The key idea is to choose the previously described matrices based on properties not in the original image.
