Quantization-Based Image Watermarking by Using a Normalization Scheme in the Wavelet Domain
To improve the invisibility and robustness of quantization-based image watermarking algorithms, we developed an improved quantization image watermarking method based on the wavelet transform and normalization strategy used in this study. In the process of watermark encoding, the sorting strategy of...
