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 …

This paper presents a robust color image watermarking algorithm based on fuzzy least
squares support vector machine (FLS-SVM) and Bessel K form (BKF) distribution, which is a …

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 …

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 …

Today, the world is going to be digitalized in all the ways. Every business units, government
and private sectors, research units are using the digital image as transferring mode for every …

It still remains a challenging problem to improve both of the imperceptibility and robustness
for the digital image watermarking task. In this study, a color image watermarking scheme is …

This paper suggests a sparse watermark image embedding scheme on the singular values
of the pre-selected wavelet sub-band coefficients of the digital images. Dictionary learning …

Data security is a main concern in everyday data transmissions over the Internet. A possible
solution to guarantee secure and legitimate transaction is via hiding a piece of tractable …

A novel approach using stationary wavelet transform (SWT) is proposed for automatically
detecting low-contrast defects under various light conditions in magnetic tile images. In this …

In this paper, a novel blind color image watermarking based on Contourlet transform and
Hessenberg decomposition is proposed to protect digital copyright of color image. Firstly …
