Sentence examples for component watermark from inspiring English sources

As the data-hiding component, watermark embedding function considers where and how to embed the watermark satisfying various requirements of the cover objects (here, digital images).

Namely, if the threshold selects too many components, the watermark may produce perceptual changes.

A watermarking algorithm in general consists of three basic components: (i) watermark, (ii) encoder (watermarking algorithm), and (iii) decoder (detection or extraction algorithm).

We encode the topological relation among components into watermarks.

where the ith watermark component is given as the sum of R entries of the LUT W k. The result of this operation is the watermarked content y k =x+w k identifying the kth user.

The insertion step follows the next formula: (1) WMI = K × (L L 3 ) + q × (W M 3 ), where WMI is low frequency component of watermarked image, LL3 is the low frequency component of the original image obtained by 3-level DWT, and WM3 is the low frequency component of Watermark image.

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.

In addition, for the characteristic of the fingerprinting protocol, frequency components and the watermark signal must be separately encrypted after quantization.

Watermarking generally operates on different digital media or cover objects (e.g., image, audio, video) and is considered to have three major components [1, 2]: watermark generation, embedding, and detection.

Indexing tables are then used to choose the location of components supporting the watermark.
