Digital halftoning is a technique for converting a continuoustone image into a binary image with the aim of reproducing it on a binary output device. Error diffusion (ED) is an algorithm that has proven to be effective for the halftoning process, and it has been widely applied to digital printing tasks. However, in images reproduced by conventional ED algorithms based on signal processing theory, the total appearance of objects—which includes properties such as glossiness, transparency, and roughness—is often lost. In this paper, we propose an appearance-preserving ED algorithm to improve the quality of printed images. We consider a texture-preserving approach to effectively represent the total appearance of objects. In this study, we utilized different weights for the error distribution based on the texture strength to permit stable representation of the pixels relevant to the texture. Experimental results using printed images demonstrated that the proposed algorithm improved the quality of printed images relative to images produced by conventional techniques.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
