  • 摘要:An Image Adaptive Watermarking method based on theDiscrete Wavelet Transform is presented in this paper.The robustness and fidelity of the proposed method areevaluated and the method is compared to state-of-the-artwatermarking techniques available in the literature. Forthe evaluation of watermark transparency, an image fidelityfactor based on a perceptual distortion metric is introduced.On the other hand, a degradation factor is introduced forthe evaluation of watermark robustness against JPEG com-pression and resizing. The new fidelity metric allows aperceptually aware objective quantification of image fi-delity. The suitability of the proposed metric for the fidelityevaluation of still image watermarking is supported by sim-ulation results
