This contribution applies tools from the information theory and soft computing (SC)
paradigms to the embedding and extraction of watermarks in aerial remote sensing (RS) …

A new hybrid chaotic map is constructed in this paper and applied to image encryption and
hiding. MD5 is used as part of initial condition and control parameter to perturb the trajectory …

This paper proposes an effective optimal blind colour image watermarking based on
Triangular Vertex Transform (TVT), Lifting Wavelet Transform (LWT) and Schur …

In this study, a literature review was presented to examine digital image watermarking
techniques based on Discrete Cosine Transform DCT. General features of the digital …

In image processing pre-processing is used for preparing or improving performance of
operations. In order to improve performance of extraction algorithms in Discrete Cosine …

With the recent development in multimedia communication network, data integrity and
security of original content is the area of concern. Video is the one of the most popular object …

An invisible robust, non blind watermarking scheme for digital images is presented. The
proposed algorithm combines the Discrete Wavelet Transform (DWT) and the Bi …

The principle objective of image enhancement is to process an image so that the result is
more suitable than the original image for a specific application. This paper presents a novel …

A robust image watermarking scheme based on human visual system is proposed. The
perceptual quality of the watermarked image is controlled by determining adaptive scaling …

De nos jours le problème des droits d‟ auteur, la vie privée et l‟ authenticité des produits
multimédia, devient un défi inquiétant. Une technique appelée tatouage numérique exploite …
