In the "Watermarking embedding" section, the watermarking embedding stage is explained.
We first preprocess I r (x, y) with the same method as in the embedding stage to give an image size of 1,024 × 1,024.
Due to the dynamic property during the watermark embedding stage, there are certain strategies/actions for each player to determine the best parameters based on its own interest.
The watermark extraction procedure at the detector's side consists of almost the same processing steps with those of the embedding stage, as illustrated in Fig. 3.
After the watermark embedding stage, encoder will send the watermarked image to the receiver via Internet or other communication channels, while the attackers would try various ways to remove or destroy the watermark if they can intercept the transmission.
This means that the watermarked and, possibly, attacked image is first geometrically normalized and feature extraction is performed in the normalized image in the same manner as in the embedding stage (using one of the methods described in Section 2.2). Figure 10 shows the result for the watermarked image of Figure 9.
All the intermediate processing stages participating in the proposed watermarking embedding phase are described next.
It is particularly noted in the end that the quantization steps computed at the embedding stage shall also be processed by the filter when the second enhancement takes effect.
At the embedding stage, watermark is embedded in the host audio signal in the third level detailed coefficient of wavelet domain which strikes a balance between the contradicting design parameters of perceptual transparency, robustness and optimized payload.
