Digital Watermarks Based on the Human Visual System
Yue Hengli · 2005
As an effective method to provide copyright protection for digital product, digital watermarking has drawn extensive attention recently. Based on the modulation transfer function (MTF) of the human visual system(HVS), this paper proposes a new scheme of digital watermarking that embedding the watermarks into the high-frequency, low-frequency and med-frequency of the image. The experimental results demonstrate its better unification between the watermarking robustness and watermarking invisibility, the watermarking with the proposed scheme is robust against noise interference and commonly used image technique.
