Adaptive 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...
متن کاملTone-dependent error diffusion based on an updated blue-noise model
The conventional blue noise model that specifies the desired noise characteristics of an ideal halftone has been updated recently and simulation results showed that the updated model can serve as a better guideline for one to develop halftoning algorithms. At the moment only a FMED-based algorithm was developed based on the updated noise model. As the algorithm does not support real-time applic...
متن کاملClustered minority pixel error diffusion
We present a clustered-minority-pixel error-diffusion halftoning algorithm for which the quantizer threshold is modified on the basis of the past output and a dot activation map. Dot area, dot shape, and dot distribution are more controllable than with other clustered-dot halftone algorithms such as Levien's algorithm. This method also effectively reduces structured mazelike artifacts in midton...
متن کاملData Hiding in Halftone Images by Dual Conjugate Error Diffusion
In this paper, we propose a new halftone watermarking method named Data Hiding by Dual Conjugate Error Diffusion (DHDCED) based on Data Hiding by Conjugate Error Diffusion (DHCED). Unlike DHCED, The proposed method will embed a binary secret pattern into two or more error diffused halftone images by modifying each of them. When the two halftone images are overlaid, the secret pattern will be re...
متن کاملWatermark Embedding for Multiscale Error Diffused Halftone Images by Adopting Visual Cryptography
Error Diffusion has been widely adopted in the printing industry due to its good visual quality and simple implementation. However, error diffusion still possesses its own deficiencies. Thus multiscale error diffusion (MED) has been developed, and this method outperforms traditional error diffusion according to extensive research results. The majority of previous halftone image watermarking tec...
