Sentence examples for model a watermark from inspiring English sources

Like the functions, G and E, the internal design of D can also vary, but it generally takes watermarked image data, ī, original image data, i and a watermark, w to yield either an estimated image data, ĩ, message m ~ and other image data, j ~, or a failure, ⊥.

In the proposed watermarking model, the spreading watermark signal and a multi-bit watermark message can be inserted into the host signal simultaneously.

In other words, by determining the required (watermarking) inputs, outputs, and properties for different objectives, this model helps characterize a watermarking scheme.

Remember that such a watermark is modeled as a Gaussian signal with zero mean.

In ACOCOA scheme, a stochastic image model for watermark embedding is adopted by using the NVF which characterizes the local image properties.
