Watermarking Scheme

A chaotic digital watermarking scheme based on logistic mapping is tested by experiments. Being of human visual system(HVS) masking properties, the watermarking adapt itself into the image, which ensure the watermark is invisible. Experimental results show that the proposed algorithm has good robustness for the common signal distortion (adding salt & pepper noise, median filtering, etc.) and geometric distortion (lossy compression, shear, etc).

Watermarking Scheme

A chaotic digital watermarking scheme based on logistic mapping was introduced. In the frequency domain, the chaos sequence embedded in DC component DC through using discrete cosine transform (DCT). Being of human visual system(HVS) masking properties, the watermarking adapt itself into the image, which ensure the watermark is invisible.
