Noise addition results on watermarked images. (a) The watermarked image in which pixels from different locations are corrupted or cropped with the white pixels. (b) The watermarked image in which salt and pepper noise with density equal to 0.05 is added. (c) The watermarked image in which salt and pepper noise with density equal to 0.1 is added to further test the robustness.
