In this work, for the first time, a blind multichannel multiplicative color image watermarking scheme in the sparse domain is proposed. In order to take into account the cross-correlation between the coefficients of the color bands in sparse domain, a statistical model based on the multivariate Cauchy distribution is used. The statistical model is then used to derive an efficient closed-form decision rule for the watermark detector. Experimental results as well as theoretical analysis are presented to validate the proposed watermark detector. The performance of the proposed detector is compared to that of the other detectors. The results demonstrate the improved detection rate and high robustness against the commonly-used attacks such as JPEG compression, salt & pepper noise, median filtering and Gaussian noise.
