Fidelity and Robustness Analysis of Image Adaptive DWT-based Watermarking Schemes

An Image Adaptive Watermarking method based on the Discrete Wavelet Transform is presented in this paper. The robustness and fidelity of the proposed method are evaluated and the method is compared to state-of-theart watermarking techniques available in the literature. For the evaluation of watermark transparency, an image fidelity factorbased on a perceptual distortion metric is introduced. This new metric allows a perceptually aware objective quantification of image fidelity.
