Robust Adaptive Image Watermarking using Visual Models in ...
In this study, two image adaptive invisible digital watermarking algorithms based on DWT and DCT are proposed for copyright protection. The first proposed algorithm utilizes Watson’s visual model (JND) to determine the watermarking strength necessary to invisibly embed the watermark in the DCT block coefficients of the cover image by ......

An improved robust image watermarking by using different ...
Image watermarking technique is an alternative solution to protecting digital image copyright. This paper proposed a new embedding technique based on different embedding strengths for embedding a watermark. An image is divided into non-overlapping blocks of 8 × 8 pixels. The variance pixel value was computed for each image block. Image blocks with the highest variance value were selected for ......
Copyright Protection for Digital Colour Images Using Dual ...
The main objective of the majority of research in Digital Image Watermarking technique is to improve the robustness of attacks.In this paper, a new algorithm has been proposed based on Discrete Wavelet Transform, Discrete Cosine Transformation in association with Singular Value Decomposition for embedding the dual watermark which provides an efficient copyright protection.Here the primary ......
Secure and Robust Digital Watermarking: A Survey
A digital watermarking technique is a multi-scientific discipline which is developed rapidly in last several years for digital content protection, such as copyright protection, authentication protection, source tracing, etc. However, in realistic scenarios, the digital watermarking system faces significant secure issues, for example, the attackers want to remove, detect, or embed illegal ......
