TLDR
A novel oblivious and highly robust watermarking scheme using Multiple Descriptions (MD) and Quantization Index Modulation (QIM) of the host image and superior in terms of Peak Signal to Noise Ratio (PSNR) and Normalized Cross correlation (NC).Abstract:
Summary A novel oblivious and highly robust watermarking scheme using Multiple Descriptions (MD) and Quantization Index Modulation (QIM) of the host image is presented in this paper. The watermark is embedded in the Discrete Contourlet Transform domain (CT). Discrete Countourlet Transform (CT) is able to capture the directional edges and contours superior to Discrete Wavelet Transform (DWT). Watermark embedding is done at two stages for achieving robustness to various attacks. This algorithm is highly robust for different attacks on the watermarked image and superior in terms of Peak Signal to Noise Ratio (PSNR) and Normalized Cross correlation (NC). here the part of summary.read more

A study of multiplicative watermark detection in the contourlet domain using alpha-stable distributions.
TL;DR: A novel multiplicative watermarking scheme in the contourlet domain using the univariate and bivariate alpha-stable distributions is proposed and the robustness of the proposed bivariate Cauchy detector against various kinds of attacks is studied and shown to be superior to that of the generalized Gaussian detector.

A new multiplicative watermark detector in the contourlet domain using t Location-Scale distribution
TL;DR: This study uses the likelihood ratio decision rule and t-location scale distribution to design an optimal multiplicative watermark detector that showed higher efficiency and robustness against different attacks, and derives the receiver operating characteristics (ROC) analytically.

Features Classification Forest: A Novel Development that is Adaptable to Robust Blind Watermarking Techniques
Chia-Sung Chang,Jau-Ji Shen +1 more
TL;DR: A novel watermarking scheme that exploits the features of micro images of watermarks to build association rules and embeds the rules into a host image instead of the bit stream of the watermark, which is commonly used in digital water marking.

A highly robust two-stage Contourlet-based digital image watermarking method
TL;DR: Since watermark is embedded in the local as well as global CT coefficients of two different frequency bands, the proposed method is robust against a wide range of attacks.

DCT-based image watermarking using subsampling
TL;DR: A DCT-based image watermarking algorithm is described, where the original image is not required for watermark recovery, and is achieved by inserting the watermark in subimages obtained through subsampling.

Digital watermarking and information embedding using dither modulation
Brian Chen,Gregory W. Wornell +1 more
TL;DR: A new class of embedding methods called quantization index modulation (QIM) is proposed and an example of such a method called dither modulation is developed in which the embedded information modulates the dither signal of a dithered quantizer.

Blind image data hiding based on self reference
Yulin Wang,Alan Pearmain +1 more
TL;DR: This paper presents a kind of blind watermarking technique, which is based on relative modulation of the pixel value/DCT coefficient value by referring to its estimated one, and reveals extraordinary robustness against numerical attacks, such as noise addition, filtering and JPEG compression.

On the security of an SVD-based ownership watermarking
TL;DR: This paper proposes to generate the watermark from the original image and owner's logo with a one-way function to defend against a counterfeiting attack on an SVD-based ownership watermarking scheme.

TL;DR: Experimental results show that the proposed scheme yields stronger AC peaks than the spatial domain scheme does and, as a result, shows improved robustness against combined geometric-removal.
