TLDR
Performance in terms of invisibility and robustness of the proposed algorithm is better than that applying on DCT-DWT combined domain for the lossy JPEG compression attacks, speckle and Gaussian noise.Abstract:
The paper proposes an image watermarking algorithm on curvelet transform domain. Different from other conventional methods which embed the watermark in spatial domain, discrete cosine transform (DCT), or discrete wavelet transform (DWT), the present paper uses curvelet transform domain for image watermarking since curvelet transform is effective when representing curves with fewer coefficients than other transforms such as wavelets for the same accuracy. The paper will investigate the different scales of curvelet transform domain for embedding the watermark to achieve both invisibility and robustness. The performance of image watermarking in curvelet transform domain is compared with the same algorithm but applied on DCT-DWT combined domain. Peak signal-to-noise ratio (PSNR) and normalized correlation (NC) are used to evaluate the invisibility and the robustness of the algorithms, respectively. Experimental results show that invisibility and robustness are ensured. Performance in terms of invisibility and robustness of the proposed algorithm is better than that applying on DCT-DWT combined domain for the lossy JPEG compression attacks, speckle and Gaussian noise.read more

TL;DR: The primary advantage of the framework is that the picture is moved before installing of the stego picture and de-moved subsequent to inserting and the easygoing of a powerful assault on the StegO picture by an aggressor is less because of utilization of this Modified Zernike strategy.

Robust watermarking in curvelet domain for preserving cleanness of high-quality images
TL;DR: A watermarking technique that maximizes invisibility while maintaining sufficient robustness and data capacity to be applied in real situations is proposed and showed very good results of a 57.65 dB peak signal-to-noise ratio in fidelity tests, and the mean opinion score showed that images treated with the proposed method were hardly distinguishable from the originals.

TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
