Abstract:

The human eye has different sensitivity to the red,green,and blue in the HVS.The human eye is least sensitive to the blue component,so the embedded watermark has a good transparency.But in the red component of the embedded watermark is robust.In order to solve the problem of visual distortion in watermarking,we take a watermark embedding scheme that different color corresponding to different weighting coefficients.While the color watermark image is embedded in the host image color as well as multiple embedded low frequency bands to increase the robustness of the algorithm.Simulation results show that the algorithm has good transparency and good watermark extraction.
