Novel dynamic color image watermarking based on DWT-SVD and the human visual system
TL;DR: A novel dynamic color image watermarking based on discrete wavelet transform (DWT) and singular value decomposition (SVD) and a semi-blind scheme avoiding at the same time the false positive error known by most of the SVD schemes and ensuring more security the authors.

Region-Based Hybrid Medical Image Watermarking Scheme for Robust and Secured Transmission in IoMT
TL;DR: In this article , the authors proposed a region-based hybrid medical image watermarking (MIW) scheme to ensure the authenticity, authorization, integrity, and confidentiality of the medical images transmitted through a public network in IoMT.
Journal ArticleDOI
Artificial bee colony based perceptually tuned blind color image watermarking in hybrid LWT-DCT domain
TL;DR: Experimental results show that the color watermark is undetectable into the host image and robust enough to resist the image processing and manipulation attacks.
Journal ArticleDOI
Optimised robust watermarking technique using CKGSA in DCT-SVD domain
TL;DR: In this article, the chaotic k-best gravitational search algorithm is used to obtain the optimal values of embedding factors to maintain the imperceptibility and robustness simultaneously, and the experimental results validate that the proposed technique outperforms the other considered techniques.
Journal ArticleDOI
Difference operators and generalized discrete fractional transforms in signal and image processing
TL;DR: In this article, generalized discrete transforms that extend the known discrete-type transforms and introduce new types as well are presented. And the strengths of the proposed transforms are demonstrated through numerical simulations and applications in image encryption and watermarking.

Differential Evolution – A Simple and Efficient Heuristic for Global Optimization over Continuous Spaces
Rainer Storn,Kenneth Price +1 more
TL;DR: In this article, a new heuristic approach for minimizing possibly nonlinear and non-differentiable continuous space functions is presented, which requires few control variables, is robust, easy to use, and lends itself very well to parallel computation.
Journal ArticleDOI
Secure spread spectrum watermarking for multimedia
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.

Robust image watermarking in the spatial domain
Nikos Nikolaidis,Ioannis Pitas +1 more
TL;DR: A copyright protection method that is based on hiding an ‘invisible’ signal, known as digital watermark, in the image is presented and a variation that generates image dependent watermarks as well as a method to handle geometrical distortions are presented.
