It is a challenging work to design a robust localized color image watermarking scheme
against desynchronization attacks. There are two main drawbacks indwelled in current …

Desynchronization attacks that cause displacement between embedding and detection are
usually difficult for watermark to survive. It is a challenging work to design a robust image …

Most of the existing color image watermarking schemes were designed to mark the image
luminance component only, which have some disadvantages:(i) they are sensitive to color …

To protect the copyright of the color image, a color image watermarking scheme based on
quaternion discrete Fourier transform (QDFT) and tensor decomposition (TD) is presented …

It is a challenging work to design a robust color image watermarking scheme against
geometric distortions. Moments and moment invariants have become a powerful tool in …

Moments and moment invariants have become a powerful tool in gray image watermarking.
More recently, a few moment-based approaches were developed to embed watermark into …

A robust watermarking method depending on Quaternion Hadamard Transform (QHT) and
QR decomposition is proposed. The QHT can preserve the relationship among the rgb …

Based on quaternion Hadamard transform (QHT) and Schur decomposition, a novel color
image watermarking scheme is presented. To consider the correlation between different …

In this paper, we propose a blind color image watermarking scheme based on quaternion
discrete Fourier transform (QDFT) and on an improved uniform log-polar mapping (IULPM) …
