Color image watermarking using SVD
Digital watermark is an important technology for the image verification. Many authors researching on color image watermarking opine RGB color space in the spatial domain is not suitable for embedding marks. In this paper, we propose a digital color image watermarking method using Singular Value Decomposition (SVD). The whole process including embedding and extracting could be finished in RGB components in spatial domain. Simulation results show that our method is successful in resolving the rightful ownership of the watermarked image with good robustness, good imperceptibility and higher security.
