In this paper, we have reviewed the state-of-art of the various wavelet based image
watermarking techniques in spatial as well as in transform domain based on the robustness …

Due to rapid development of Internet and computer technology, image authentication and
restoration are very essential, especially when it is utilized in forensic science, medical …

In recent years, many works on digital image watermarking have been proposed all aiming
at protection of the copyright of an image document or authentication of data. This paper …

Digital watermarking is used to protect copyright information by embedding hidden data in
digital media. In this study, a multiplicative watermarking scheme is proposed in the …

Increasing the robustness, reliability and security of the digital image watermarking methods
against image processing and geometrics attacks are a key issues especially for image …

The vector-based hidden Markov model (HMM) is a powerful statistical model for
characterizing the distribution of the wavelet coefficients, since it is capable of capturing the …

In the past decade, several schemes for digital image watermarking have been proposed to
protect the copyright of an image document or to provide proof of ownership in some …

In this paper, we propose a blind robust image watermarking approach in the
nonsubsampled Shearlet domain using Bessel K Form (BKF) modeling. Nonsubsampled …

Imperceptibility and robustness are two main requirements of any image watermarking
systems to guarantee desired functionalities, but there is a tradeoff between them from the …

In this paper, a new Quaternion Discrete Fourier Transform (QDFT)-based digital color
image watermarking method is presented. In addition, the Quaternion QR (QQR) …
