Heteroscedastic watermark detector in the contourlet domain

Heteroscedastic watermark detector in the contourlet domain

A new contourlet domain image watermark detector is proposed in the present study. As the performance of the detector completely depends on the accuracy of the statistical model, the contourlet coefficients and statistical properties are studied first. The heavy‐tailed distribution and heteroscedast...
