چکیده
Image watermarking technique embeds copyright information (watermark) into host image so as to perform its protection and authentication. Schemes of embedding digital watermark into grayscale images have been researched and developed greatly. However color image is more common in our everyday life and it contains more information than grayscale image and provides information to against the attack of illegal copyright. So it is very important to embed the watermarking into color image for copyright protection. This paper presents a critical review of existing methods of Color Image Watermarking in recent years. This literature review concludes with the concept of betterment of algorithms and scope of its future direction of research.

Research on Color Watermarking Algorithm Based on RDWT-SVD
In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...
