Sentence examples for data of the watermark from inspiring English sources

As mentioned before, all components of the watermark are embedded and no extra data of the watermark remain to be preserved out of the host image.

Table 7 presents BER data for each of the watermark parameters for various communication channels.

where and are the short-time Fourier transforms of the multidimensional watermarked data, the host data, and the watermark, respectively.

Removal attacks aim at the complete removal of the watermark information from the watermark data without cracking the security of the watermarking algorithm [20].

Robustness [ 9] is the resistance of the watermark system against intentional transformations of the watermarked image.
