Digital image watermarking provides security, copyright protection, and authenticity to
multimedia content by embedding digital content like text, image, and video. In the modern …

The leapfrog development of computer technology has greatly enhanced the breadth of
information dissemination. As a larger information carrier, color image becomes more and …

Most of the existing color image watermarking schemes are designed to mark each color
channel individually, which ignores the correlation of different color channels and the …

In this study, a high-capacity QR decomposition (QRD) based blind watermarking algorithm
with artificial intelligence (AI) technologies for color images was proposed. Watermarking …

Compared with binary and grayscale watermark, the color watermark has a larger amount of
information, which makes color blind watermarking algorithms more challenging in terms of …

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 …

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 …

Image watermarking is a robust solution for solving key issues like copyright protection and
proof of ownership of digital data. Existing schemes of image watermarking mostly used …

In this paper, an approximate Schur decomposition-based spatial domain blind color image
watermarking method is proposed to protect the copyright of color images, which has low …

In this work, a new quaternion-based method for color image watermarking is proposed. In
this method, a novel set of quaternion radial substituted Chebyshev moments (QRSCMs) is …
