In this paper, we propose a new watermarking method which spreads an ID pattern with
specific sequences and embeds it throughout the spatial domain of an image. A set of the …

It is urgently required to protect copyrights of digital contents since the digital contents can
be easily copied without degradation of quality. In this paper, we propose a new …

This letter proposes improvement to the previously presented watermarking method which
spreads an ID pattern with a random sequence and embeds it throughout the spatial domain …

This paper presents a new approach for digital image watermarking providing robustness to
geometrical distortions. As embedding watermark by the object, we can detect the …

Digital watermarking is used to hide the information inside a signal, which can not be easily
extracted by the third party. Its widely used application is copyright protection of digital …

The growth of networked multimedia systems has created a need for the copyright protection
of digital images. Copyright protection involves the authentication of image ownership and …

Digital watermarking plays an increasingly important role for proving authenticity and
copyright protection. The Internet is an ideal medium for selling digital goods it also makes …

Contourlet transform is a very efficient anisotropy analysis tool in high dimensions, which
can not only possess the main features of directionality and anisotropy, but also effectively …

In this paper, an improved second generation digital image watermarking scheme is
proposed. This scheme exploits the region feature instead of point or line feature. The region …

We present a new DCT-based block max-min algorithm for digital watermark embedding in
images. Our algorithm uses intra-block bordering upon pixels relations to generate the …
