A Color Image Watermarking Scheme in Wavelet Domain Based on Support Vector Machines

A digital watermarking method for color image in wavelet domain is proposed. The watermarking information which include a section of template information, is embedded into low-frequency coefficients of Y component in YUV color space. This section of template information defines a kind of relation between the low-frequency coefficients corresponding to the four sub-images obtained by down-sampling technique. It will make watermarking extraction turn into a two-class problem and realize the extraction of watermarking through the study of the relation based on utilizing support vector machine. Experimental results show that the proposed method has good performances and the robustness of the proposed method is superior to other methods.
