Sentence examples for more robust watermark from inspiring English sources

The results demonstrate that our proposed method yields significantly more robust watermark than the method in [10] does.

Currently, watermarking techniques based on transform domain are more popular than those based on time domain since they provide higher audio quality and much more robust watermark.

However, the algorithms using transform domain approach develop more robust watermarking techniques than directly embedding watermark into the spatial domain [3, 18].

With the aim of designing a more robust digital watermarking scheme against various unintentional and intentional attacks, a significant region (SR) based image watermarking technique is proposed in the present paper using lifting wavelet transform (LWT).

The closer to 1 NC2 value is, the more robust of watermarking algorithm is.

It is possible to embed perceptually inaudible watermarks with more energy in an audio, which makes watermark more robust [12, 17].

we can easily see the tradeoff between making the watermark logo more robust in noisy environment (less value) and making the watermarked image more identical to the original (high value).

Simulations on real images by using the wavelet-based implementations demonstrate the proposed method performs very well in both watermark imperceptibility and robustness and is more robust to typical signal processes, e.g., additive noise, JPEG compression, etc., as compared with the state-of-the-art watermarking methods.

The aforementioned three works have highly motivated the scientists to develop more robust and efficient moment-based watermarking techniques.

By using this approach, more robust, invisible, secure and high capacity watermarking algorithm is obtained.

The plots of Fig. 8 show that a more sophisticated assignment (non-blind) of the quantization steps to the moment coefficients, aiming that the inserted information is proportional to the capacity of the coefficients, can lead to more robust and of the same quality watermarked images.
