Abstract:

Based on image scrambling and pattern recognition, a new watermarking scheme in huge index image is proposed. The scaling parameter according to HVS(human visual system) was adjusted by the system while embedding watermarks. The experimental results show that the proposed scheme has a good effect of anti-cutting, anti-modifying, anti-patching and invisibility.

Key words: digital watermark, index image, image scrambling, pattern recognition
