Abstract :
In this paper, in order to control the quality of the embedded content, we propose a new domain, called q-DWT (discrete wavelet transform) for novel and robust image watermarking. We embed the watermark in the low-frequency of q-DWT domain in order to achieve the robustness of watermark. We employ the quantization index modulation (QIM) technique for embedding due to its high robustness and blindness. In our proposed method, the tradeoff of robustness and quality can be controlled by parameter Q of QIM and parameter q of the logarithm function.
