With the rapid development and popularity of the Internet, multimedia security has become a
general essential concern. Especially, as manipulation of digital images gets much easier …

Fractional Fourier transform (FRFT) is a generalization of the Fourier transform, rediscovered
many times over the past 100 years. In this paper, we provide an overview of recent …

Popular convolutional neural networks mainly use paired images in a supervised way for
image watermark removal. However, watermarked images do not have reference images in …

Popular methods usually use a degradation model in a supervised way to learn a watermark
removal model. However, it is true that reference images are difficult to obtain in the real …

Although it has been known that oblivious (or blind) watermarking schemes are less robust
than nonoblivious ones, they are more useful for various applications where a host signal is …

Because of the transition from analog to digital technologies, content owners are seeking
technologies for the protection of copyrighted multimedia content. Encryption and …

The increasing popularity of the internet means that digital multimedia are transmitted more
rapidly and easily. And people are very aware for media ownership. However, digital …

In this paper, a robust watermark scheme for copyright protection is proposed. By modifying
the original image in transform domain and embedding a watermark in the difference values …

Abstract Information hiding is to protect the security of secret information during
