Sentence examples for embedding area from inspiring English sources

Since the approximation coefficients are supposed to be relatively stable and less sensitive to slight changes of the audio signal, they are ideal embedding area.

Watermarking methods Block size of original image Mohanty's method [24] Asatryan's method [27] Proposed method   Selection embedding area procedure (1) Find a most perceptually significant set of blocks constituting a subimage (equal to size of watermark) with respect to human perception such as Texture, Location, Contrast, Luminance, and Edginess in original image.

More formally, for each embedding area g i (x, y), i = 1... M (where M is the number of feature points) of the normalized image we additively embed the DCT-domain watermark as follows D C T ( g i w ( x, y ) ) = D C T ( g i ( x, y ) ) + α ⋅ W ( u, v ) (26).

In this section, the differences and excellences of proposed method with two related methods [24, 27] are introduced in four conventional different steps of watermarking methods: (1) selecting embedding area procedure, (2) watermark creation procedure, (3) inserting procedure, (4) extracting procedure.

where i = 1,..., M, w i (x, y) is the image with same size as f x, y) and non-zero only in the i th embedding area (where w o is located), and f 0 w ( x, y ) = f ( x, y ).

We prefer to use all feature points as embedding area centers instead of applying some kind of criterion to select some of them.

We can notice that some embedding areas may overlap because of the proximity of the corresponding feature points.

The next step is to extract a set of feature points that will act as centers of the watermark embedding areas.

This module also supports the implementation of an optional 'dropbox' feature, that constructs a webpage embedded area into which users may easily 'drag-and-drop' XGMML files for automatic parsing and subsequent visualization.

The encryption of the watermark and the choice of embedded areas based on the perceptivity not only confer the watermark with good invisibility but also with good robustness.

Humans have reshaped more than three quarters of the terrestrial biosphere into anthropogenic biomes (anthromes), embedding substantial areas of remnant and recovering novel ecosystems within the agricultural and settled landscapes that sustain human populations.
