A Color Image Watermarking Scheme in the Associated Domain of DWT and DFT Domains Based on Multi-channel Watermarking Framework

We propose a watermarking scheme basedon the multi-channel watermarking framework, which ismainly used to resist geometric attacks. This watermarking scheme generates watermarking templates from oneimage transform domain which is obtained after DWT(Discrete wavelet transform) and DFT (Discrete Fouriertransform) transformation to one of image channels andthen embeds these watermarking templates into anotherimage transformation domain which is obtained after DWTand DFT transformation to another image channel. Whenthe watermarking image undergoes geometric attacks,self-synchronization can be obtained in the procedure ofdetecting watermarking, because the geometric attackswhich watermarking template and watermarking image undergo are similar. Experimental results demonstrate thatthis watermarking scheme produced by the multi-channelframework is high robust to attacks such as geometric distortion, rotation, affne, JPEG compress and adding noiseetc..
