WebMULTI-CHANNEL GREEN-NOISE MASKS The green-noise mask is a novel approach to dither array screening where a continuous-tone image is converted to a binary halftone image by performing a pixel-wise comparison between the original and the dither array or mask. Previously, halftoning with green-noise has implied error-diffusion based … WebDithering is based on a completely local determination which is both simple and fast. We first consider the easier case of black and white (BW) printing, for which the color dimension is 1. Furthermore, we assume that the index dimension is 2. A dithering mask (mask for short) is specified by an n x m matrix M of threshold coefficients M(i, j).

WebEach pattern is shown above the corresponding undithered shade. Ordered dithering is an image dithering algorithm. It is commonly used to display a continuous image on a display of smaller color depth. For example, Microsoft Windows uses it in 16-color graphics modes. The algorithm is characterized by noticeable crosshatch patterns in the result. WebIn general, an input CMYK image is provided to the screening module, which performs halftoning (e.g. dither mask halftoning) independently for each color plane. In this paper, we propose a simple but effective color halftoning algorithm with minimum dot-on-dot using DBS and its implementation on Graphics Processing Units (GPU). Recently, GPU ...
