Dual-watermarking policy based on Arnold transform and error correcting coding
Zhenhong Jia · Computer Engineering and Applications Journal · 2010
A novel dual-watermarking algorithm based on wavelet transform for color images is proposed.Firstly,the RGB color image is transformed into YIQ color space,and then the Y is decomposed with discrete wavelet transform.Arnold transform and error correcting coding are adopted in the watermarking processing,and then they are embedded into the detail sub_image.Mostly,this algorithm can also realize blind extraction.The watermark generated with proposed algorithm is imperceptible and of better robustness against common attacking processing methods.
