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 …

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 …

Most of the existing color image watermarking schemes was designed to mark grayscale
images or use the color components, which ignore the significant correlation between …

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

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 …

In this paper, a geometrically invariant color image watermarking method using Quaternion
Legendre-Fourier moments (QLFMs) is presented. A highly accurate, fast and numerically …

In this work, a new quaternion-based method for color image watermarking is proposed. In
this method, a novel set of quaternion radial substituted Chebyshev moments (QRSCMs) is …

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 …

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 …

The first adaptive moment-based color image watermarking is presented in this work. The
proposed method exploits rotation invariance, high reconstruction capability and …
