Visible Watermarking Technique Based on Human Visual System for Single Sensor Digital Cameras

Figure 10

Attacked visible watermarked artificial images (Figure 5(a)), generated by [13, 14] and proposed algorithm. ((a)–(c)) Compressed watermarked images by JPEG standard, ((d)–(f)) high contrast, ((g)–(i)) low contrast, ((j)–(l)) Gaussian low-pass filter, ((m)–(o)) high illumination, ((p)–(r)) low illumination, and ((s)–(u)) Gaussian noise contamination.
