Color diffusion: error diffusion for color halftones
color halftoning, error diffusion, minimal brightness variation criterion Error Diffusion is a high-performance halftoning method in which quanitization errors are diffused to “future” pixels. Originally intended for grayscale images, it is traditionally extended to color images by Error-Diffusing each of the three color planes independently (separable Error Diffusion). In this report we show t...
متن کاملHalftoning via Error Diffusion using Circular Dot-overlap Model
Circular dot-overlap model is one of the simplest printer models, which is used to predict the actual gray levels of printed images. Model-based halftoning can produce print outputs which can render the gray levels of original input image more correctly and keep more detail in the outputs. Cluster-dot halftoning is a classical method used to minimize dot gain. In this paper, the model-based hal...
متن کاملA mathematical description of the dot diffusion algorithm in image halftoning with application in inverse halftoning
The dot diffusion method for digital halftoning has the advantage of parallelism unlike the error diffusion method. The method was recently improved by optimization of the so-called class matrix so that the resulting halftones are comparable to the error diffused halftones. In this paper, we will give a mathematical description of the dot diffusion method. This description is then applied in in...
متن کاملError Diffusion on an Adaptive Raster
Whenever a continuous-tone image has to be displayed on a bi-level medium, some kind of halftoning has to be carried out. Nowadays processing of the continuous-tone image is often done by a computer, i.e. the sampled and quantized continuous-tone image is transformed into a binary image by a halftoning algorithm. In the following we will assume the continuous-tone image to be scaled between 0 a...
متن کاملAdaptive threshold modulation for error diffusion halftoning
Grayscale digital image halftoning quantizes each pixel to one bit. In error diffusion halftoning, the quantization error at each pixel is filtered and fed back to the input in order to diffuse the quantization error among the neighboring grayscale pixels. Error diffusion introduces nonlinear distortion (directional artifacts), linear distortion (sharpening), and additive noise. Threshold modul...
