摘要
En 中文
This study presents an optimization-based image watermarking scheme with integrated quantization embedding. First, peak signal to noise ratio (PSNR) is rewritten as a performance index in matrix form. In order to guarantee the robustness, this study embeds a watermark into the low-frequency coefficients of discrete wavelet transform (DWT). Unlike traditional way of single-coefficient quantization, this study applies amplitude quantization to embed the watermark and then rewrite this amplitude quantization as a constraint with embedding state. Then, an optimization-based equation connecting the performance index and amplitude-quantization constraint is obtained. Second, Lagrange Principle is used to solve the equation and then the optimal results are applied to embed the watermark. In detection, the hidden watermark can be extracted without original image. Finally, the performance of the proposed scheme is evaluated by PSNR and BER.
