Sentence examples for both watermark from inspiring English sources

Both watermark embedding and detection are performed in the time-frequency domain.

The preprocessing stage described in the previous section is, as already stated, common for both watermark embedding and detection procedures.

In Section 2, the initial stage of preprocessing which precedes both watermark embedding and detection is first described.

This normalized representation of the original image is the input for the next step of preprocessing that is necessary for both watermark embedding and detection.

Both watermark embedding and detection procedures require that a proper preprocessing of the original image has taken place, so that the watermark embedding or detection areas can be located.
