Watermarking, which belong to the information hiding field, has seen a lot of research
interest. There is a lot of work begin conducted in different branches in this field …

In this article, a new scheme based on a combination of DWT, DCT, and SVD domains is
presented, in which the main focus is to provide proper solutions for reducing effect of …

In this paper we applied differential evolution (DE) algorithm to balance the tradeoff between
robustness and imperceptibility by exploring multiple scaling factors in image watermarking …

This paper presents a new semi-blind reference watermarking scheme based on discrete
wavelet transform (DWT) and singular value decomposition (SVD) for copyright protection …

The performance of differential evolution (DE) algorithm is significantly affected by its
parameters setting that are highly problem dependent. In this paper, an optimal discrete …

Although the particle swarm optimisation (PSO) algorithm requires relatively few parameters
and is computationally simple and easy to implement, it is not a globally convergent …

A new wavelet based logo-watermarking scheme for copyright protection of digital image is
presented. Instead of using a noise type Gaussian sequence, a visually meaningful gray …

In this paper, a robust watermarking technique is proposed using integer discrete cosine
transform, non-linear chaotic map and dynamic stochastic resonance (DSR). Firstly, the host …

Digital watermarking embeds a watermark to minimise the problem of illegal copying and
disseminating multimedia contents. However, the existing techniques do not maintain the …

This paper shows that an image can be approximately reconstructed based on the output of
a blackbox local description software such as those classically used for image indexing. Our …
