In this paper we present a model-based image steganography method in discrete wavelet
transform (DWT). This method is based on the human visual system model. The proposed …

This paper presents a model‐based image steganography method based on Watson's
visual model. Model‐based steganography assumes a model for cover image statistics. This …

The protection of copyrights of digital images authors is one of the most important tasks set
before watermarking. What is especially important is to ensure the high robustness of a …

Watermarking protects legitimate copies of digital multimedia, such as video, audio and
images, from unauthorized use. Digital watermarks are used to verify the authenticity …

This chapter discusses the different strategies to ensure the invisibility of a message
embedded in a color image. It focuses on the watermarking of color images that involves the …

Digital watermarking is a concept of embedding authentication information. It uses an
algorithm for inserting a watermark to protect the copyright of media. It became very …

Digital watermarking is a technique for embedding a secret signal (watermark) into a host
signal in an imperceptible fashion, aiming to serve as a signature for the identity or …

With the growth of multimedia technology huge amount of digital data are exchanged in
internet but digital data can be duplicated by unauthorized users. To avoid this problem the …

L'apprentissage automatique utilisant des réseaux neuronaux profonds appliqués à la
reconnaissance d'images fonctionne extrêmement bien. Néanmoins, il est possible de …
