A bind RGB color image watermarking based on singular value decomposition

In this paper, we propose a novel SVD-based RGB color image watermarking, in which the watermark is assumed to be an RGB color image whose detection and extraction are performed in a blind manner. The performance of the proposed watermarking method is investigated by measuring its imperceptible and robust capabilities. For the imperceptible capability, a quantitative index, Peek Signal-to-Noise Ratio (PSNR), is employed to evaluate the difference between an original image and its corresponding watermarked image. For the robust capability, the Correlation Coefficient (CC) is also used to evaluate the similarity between the original watermark and the extracted one. Experimental results indicate that our technique is robust and produces high-quality watermarked images.
