In this paper, we propose a novel watermarking based on $q$-SVD domain. We embed the watermark into the low-frequency of $q$-SVD domain in order to achieve the robustness of watermark. We also choose in our method a watermarking technique in the category of Quantization Index Modulation (QIM) due to its good robustness and blind. In our proposed method, the tradeoff of robustness and quality can be controlled by a predefined quantization coefficient $Q$ of QIM and $q$ parameters of logarithm transform. |
