Graph-order dithering

Alejo Hausner, Reiner Eschbach, Gabriel G. Marcu
2006 Color Imaging XI: Processing, Hardcopy, and Applications  
Concatenating the subsets yields a dither matrix that reproduces a motif while displaying an overall image.  ...  It also improves artistic halftoning, by extending the range of viable motif images that may be repeated when reproducing an overall image.  ...  As far as the present author is aware, graph ordering has not been previously applied to the problem of halftoning.  ...

Geometry-aware scattering compensation for 3D printing

2019 ACM Transactions on Graphics  
In addition, we propose a content-aware gamut mapping that significantly improves color reproduction for the pathological case of thin geometric features.  ...  Using an accurate volumetric Monte Carlo appearance prediction, they have achieved important fidelity improvements, albeit only for axis-aligned slab geometry.  ...  They are consistent with the renderings (d) and also demonstrate the achieved improvement. Figure 13 demonstrates the effect of content-aware gamut mapping on a generally-shaped model.  ...

Importance Driven Halftoning

L. Streit, J. Buchanan
1998 Computer graphics forum (Print)  
Pen-and-ink illustration can be closely paralleled with the process of halftoning.  ...  An excess of display primitives can be used to emphasize contrast.  ...  Dither: In halftoning, the arrangement of pixels within an area, also known as spatial dithering. Dot-gain: Overlap of one pixel into another. Common in bleeding of ink on laser printers.  ...

Halftoning and Stippling [chapter]

Oliver Deussen, Tobias Isenberg
2012 Computational Imaging and Vision  
Stippling Stippling is an illustration technique that relies on dots. In contrast to halftoning methods, dots are distributed manually.  ...  Figure 3 .Fig. 3. 3 33 3(b) shows the improvement in the visual output.Many other halftoning techniques have been developed.  ...

Tangent-Based Binary Image Abstraction

Yi-Ta Wu, Jeng-Sheng Yeh, Fu-Che Wu, Yung-Yu Chuang
2017 Journal of Imaging  
Winnemöller et al. [3] presented an automatic, real-time abstraction framework that abstracted images by modifying the contrast of visually important features.  ...  Thus, clarifying the significant structures in an image is an important task for image abstraction.  ...  Yung-Yu Chuang is as an advisor guiding the designing of image processing methods.  ...

GIFnets: Differentiable GIF Encoding Framework [article]

Innfarn Yoo and Xiyang Luo and Yilin Wang and Feng Yang and Peyman Milanfar
2020 arXiv   pre-print
Each of these three networks provides an important functionality within the GIF encoding pipeline. PaletteNet predicts a near-optimal color palette given an input image.  ...  DitherNet manipulates the input image to reduce color banding artifacts and provides an alternative to traditional dithering.  ...  Li and Mould [22] alleviated contrast varying problems using contrast-aware masks.  ...

Color gamut mapping and the printing of digital color images

Maureen C. Stone, William B. Cowan, John C. Beatty
1988 ACM Transactions on Graphics  
Included also are some details on monitor and printer calibration, and a brief description of how digital halftone screens for offset printing are prepared.  ...  An image is represented as a set of three-dimensional points, and the color output device as a three-dimensional solid surrounding the set of all reproducible colors for that device, called its gamut.  ...  To improve contrast, a fourth ink, black, is often added.  ...

Magic sheets: Visual cryptography with common shares

Naoki Kita, Kazunori Miyata
2018 Computational Visual Media  
Visual cryptography (VC) is an encryption technique for hiding a secret image in distributed and shared images (referred to as shares).  ...  We propose an approach to hide multiple images in meaningful shares. We can decrypt multiple images simultaneously using a common share, which we refer to as a magic sheet.  ...  Contrast-aware halftoning [22] or other stateof-the-art error diffusion approaches [23] could also be employed for faster and better image preparation.  ...
