| Unfortunately, high payload has to be achieved at the expenses of imperceptibility as well. |
|
| For 15 minutes, the three men essay an ambient drone, its shifts and slow builds so gradual they are almost to the point of imperceptibility. |
|
| Finally, we will investigate the tradeoffs among data imperceptibility, data hiding capacity, and probabilities of extraction errors in different applications. |
|
| Can you pay the price for risking perception and imperceptibility? |
|
| The imperceptibility of a pigeon's nest is essential, as they want neither man nor peregrine falcon alerted to their presence. |
|
| The estimated watermark is adopted to the local features of the target data to satisfy its imperceptibility. |
|
| In terms of its effect, there is little noticeable difference between, say, a 1.0 and 2.0 – these cause tremors that vary only in degree of imperceptibility. |
|
| Sea urchins rippled their spines with the imperceptibility of a clock's minute hand. |
|
| It is this invisibility, this imperceptibility of pain, that is striking in the play in the same way as in the photographs themselves. |
|
| Imperceptibility is referred to the perceptual difference between the stego and original image and can be tested subjectively. |
