Abstract: This paper presents a reference watermarking scheme in which both original and watermark images are RGB color images. Reference images are obtained from red, green and blue components of the original image by using Discrete Wavelet Transform (DWT) and Directive contrast. Singular Value Decomposition (SVD) is applied on each of the component images (Red channel, Green channel and Blue channel) of watermark and reference images (red, green and blue). Watermark is embedded by modifying the singular values of the reference images with the singular values of the watermark component images. A reliable watermark extraction scheme is developed. Experimental results show that the proposed scheme survives against common signal/image processing attacks. © Springer India 2014.
