Study on Moiré Fringe of halftone image and its influence on image optical representation effect
2010 Edition, Volume 5, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The reasons of Moiré Fringe of halftone image were analyzed and the rules of Moiré Fringe distribution, e.g., the screening frequency influence on Moiré Fringe and the screening angle...

Halftone Image Watemarking
2007 Edition, November 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we present a new and simple watermarking algorithm for halftone images. The method is based on the principle of error diffusion techniques for halftoning in order to embed a watermark to by creating a second image (a key type) from the...

Steganalysis of halftone images
2005 Edition, Volume 2, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a novel steganalysis technique for halftone images without knowledge of the original cover image. We first convert halftone images into grayscale-like images by low-pass filtering. The low-pass-filtered image is then decomposed...

Local binary pattern on halftone image
2017 Edition, October 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents an efficient and effective way on computing the Local Binary Pattern (LBP) feature from the halftone image for the image retrieval and classification tasks. The Ordered Dither Block Truncation Coding (ODBTC) compresses an image...

A new edge enhancement on halftone image
2011 Edition, April 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a new algorithm for improving the qualities of edge in halftone image. The algorithm is designed to diminish discontinuous and jaggy artifact on edges of halftone image without original image data. And our...

New Steganography Scheme in Halftone Images
2008 Edition, August 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A so-called DHCED (Data Hiding by Conjugate Error Diffusion) method was proposed to hide a binary visual secret into halftone images such that the watermarked halftone image still has good visual quality. When decoding, the secret can be visually revealed by directly...

Watermarking technique for color halftone images
2004 Edition, Volume 3, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose a method to hide invisible patterns in color error diffused halftone images. The hidden pattern is embedded in different color components. The hidden patterns would be revealed when the watermarked color halftone images are under Boolean...

A symmetric key watermark for halftone images
2003 Edition, Volume 3, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In many printer and publishing applications, it is desirable to embed data in halftone images for copyright control and authentication purposes. While intentional attacks on printed matters may not be likely, unintentional attacks such as cropping and...

A robust public watermark for halftone images
2002 Edition, Volume 3, January 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In many printing and publishing applications, it is desirable to embed data in halftone images for copyright control and authentication purposes. While intentional attacks on printed matter may not be likely, unintentional attacks such as cropping and...

Data hiding in dot diffused halftone images
2011 Edition, July 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose two halftone image watermarking methods. Data Hiding by Conjugate Dot Diffusion (DHCDD) and Data Hiding by Dual Conjugate Dot Diffusion (DHD-CDD). DHDCDD is an improved method of DHCDD. Both of these two methods can embed a secret pattern...
