With the rapid development of computer technology, the copyright protection of color image
is becoming a more and more urgent problem. In this paper, an improved color image blind …

The widespread application of the Internet makes the protection of image copyright face
serious challenges. For resolving this problem, this paper designs a blind color digital image …

Most of the existing color image watermarking schemes use binary or gray-level image as
watermark, and many of them belong to non-blind watermarking methods. It is a challenging …

In order to protect the color image copyright protection of the multimedia big data, it is
necessary to design a color image watermarking algorithm. To achieve this purpose, an …

In this study, a novel blind image watermarking technique using Hessenberg decomposition
is proposed to embed colour watermark image into colour host image. In the process of …

This paper proposes a new algorithm of blind color image watermarking based on LU
decomposition. Because of the first column the second row element and the first column the …

A novel colour image watermarking scheme based on Schur decomposition is proposed in
this paper. By analysing the 3× 3 unitary matrix U via Schur decomposition, the strong …

At present, the binary images are often used as the original watermark images of many
watermarking methods, but partial methods cannot be easily extended to colour image …

Most of the existing color image watermarking schemes use binary or grayscale image as
watermark, and many of them belong to non-blind watermarking methods. In this paper, an …

In this paper, a new image blind watermarking method based on two-dimensional Discrete
Cosine Transform (2D-DCT) is presented to realize copyright protection of color image. At …
