Abstract. [...] Key Method While a randomization is applied to remove the structural artifact in the flatten area, a gradient-based diffusion modulation is applied to enhance the real structures in the detailed area. Furthermore, tone modulations are introduced to achieve sufficient structural-artifact breaking without producing notable noise. These algorithms are simple and maintain the computational efficiency of the original methods. Numerical experiments show that this method is not only outperforming…Expand
Noise shaping for direct binary search image halftoning
TLDR
Experimental results show that both the spatial-domain and frequency-domain characteristics of the generated halftone pattern can be manipulated freely using the “noise shaping” approach to DBS clustered-dot halftoning.
Halftone spatial frequency domain imaging enables kilohertz high-speed label-free non-contact quantitative mapping of optical properties for strongly turbid media
TLDR
A new imaging modality termed halftone spatial frequency domain imaging (halftone-SFDI) is developed, which is approximately two orders of magnitude faster than the state-of-the-art, and provides kilohertz high-speed, label-free, non-contact, wide-field quantification for the optical properties of strongly turbid media.

TLDR
A modified error-diffusion halftoning scheme is proposed that the error is diffused dynamically according to the magnitude of gradient and the proposed impact functions, which can enhance the edges and preserve the smooth regions.
Improving mid-tone quality of variable-coefficient error diffusion using threshold modulation
TLDR
Experiments show that, compared with the original variable-coefficient error-diffusion algorithm, threshold modulation can remove visual anomalies more effectively and Fourier analysis of the experimental results further support this conclusion.

TLDR
An iterative algorithm is developed that searches the brightest region of a given image via "maximum intensity guidance" for assigning dots and diffuses the quantization error noncausally at each iteration to measure the quality of halftone images.
