Yuan Ling · Journal of Kashgar Teachers College · 2011
Based Curvelet,a blind watermarking of color digital image algorithm is given.The algorithm use Arnold chaotic system to scrambling watermarking image,and based HVS use Curvelet transformed initial image's Q component,blocked the low frequency component and SVD.The watermarking is embedded into the most SVD.The large amount of emulation experiment indicates that the algorithm is good blind watermark algorithm.
