Trade-Off between Imperceptibility and Robustness of LSB Watermarking Using SSIM Quality Metrics

This paper investigates trade-off between imperceptibility and robustness of LSB watermarking. LSB algorithm is one of the earliest types of image watermarking. In this algorithm significant bit-planes of the watermark image are put instead of lower bit-planes of the asset picture. So, we investigate the effect of image compression on the watermark, and finally we evaluate the robustness and imperceptibility by measuring the distortion due to watermarking using two quality metrics: MSE and 1 - SSIM.
