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 …

Since the first edition of this book was published several new developments have been
made in the field of the moiré theory. The most important of these concern new results that …

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 …

Halftone visual cryptography (HVC) enlarges the area of visual cryptography by the addition
of digital halftoning techniques. In particular, in visual secret sharing schemes, a secret …

We consider the problem of document binarization as a pre-processing step for optical
character recognition (OCR) for the purpose of keyword search of historical printed …

This paper introduces the concept of QR images, an automatic method to embed QR codes
into color images with bounded probability of detection error. These embeddings are …

Multi-shot coded aperture snapshot spectral imaging (CASSI) systems capture the spectral
information of a scene using a small set of coded focal plane array (FPA) compressive …

In this article we survey techniques for the digital simulation of hand-made stippling—one of
the core techniques developed within non-photorealistic/expressive rendering. Over the …

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 …

In this article, we review the spatial and spectral characteristics of blue-and green-noise
halftoning models. In the case of blue noise, dispersed-dot dither patterns are constructed by …
