Watermarking for the digital images based on model of human perception

As an effective method to provide copyright protection for digital media, digital watermarking has drawn extensive attention recently. The paper proposes a scheme of digital watermarking based on the modulation transfer function (MTF) of the human visual system(HVS). 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.
