Halftoning is the rendition of continuous-tone pictures on displays, paper or other media that
are capable of producing only two levels. In digital halftoning, we perform the gray scale to …

The late 1980s, revolutionary advances in digital halftoning enabled inkjet printers to
achieve much higher image fidelity. The rapid rate of progress has resulted in numerous …

A model for the human visual system (HVS) is an important component of many halftoning
algorithms. Using the iterative direct binary search (DBS) algorithm, we compare the …

In this paper, we review a number of techniques for fuzzy color quantization. We show that
the fuzzy membership paradigm is particularly suited to color quantization, where color …

The direct binary search (DBS) algorithm employs a search heuristic to minimize the mean-
squared perceptually filtered error between the halftone and continuous-tone original …

Unlike the error diffusion method, the dot diffusion method for digital halftoning has the
advantage of pixel-level parallelism. However, the image quality offered by error diffusion is …

We present an enhanced error diffusion halftoning algorithm for which the filter weights and
the quantizer thresholds vary depending on input pixel value. The weights and thresholds …

Image watermarking concerns embedding information in images, in a manner that does not
affect the visual quality of the image. This paper focusses on watermarking of dither halftone …

Digital halftoning is the process of generating a pattern of pixels with a limited number of
colors that, when seen by the human eye, is perceived as a continuous-tone image. Digital …

The direct binary search (DBS) algorithm is one of a family of iterative approaches to signal
design. DBS is characterized by a particular search strategy and an efficient approach to …
