The paper presents a technique which thresholds the noise directly. The threshold is modified at each step such that the expected value of the output is equal ...
ABSTRACT. Approaches for digital halftoning of images using dithering threshold the input image with additive dithering noise.
Effective digital halftoning can substantially improve the quality of rendered images at minimal cost. Page 2. C. A. Bouman: Digital Image Processing - January ...
Threshold the sum of the image and mask at the mid-gray value of 1 to produce a bitonal image of the object such that the halftone pattern is dominated by less- ...
Dithering with blue noise (i.e. high-frequency noise) attempts to place the quantization noise from the halftoning process into the higher frequencies.
3 Thresholding and Random Noise Binarization. The simplest method of converting a grayscale image to a binary image is by thresholding,. i.e. a two-level (one ...
In this paper we present a novel digital halftone process in which the halftoning is achieved by a pixelwise comparison of the gray-scale image with an array, ...
