Many new DCT-like transforms have been proposed since the first edition of this book. For
example, the integer DCT that yields integer transform coefficients, the directional DCT to …

We consider a self-managing, self-organizing pool of virtualized computer servers that
provides infrastructure as a service (IaaS) for enterprise computing workloads. A global …

Steganography is a science that focuses on hiding specific messages using specialized
techniques in such a way as only the sender and the intended receiver are able to decipher …

This paper presents a method for blind digital watermarking of color images. The proposed
scheme performs a decorrelation of the RGB color bands of the image to be watermarked …

The paper presents a fragile watermarking technique that may be used to discover image
manipulations at block level. The proposed algorithm, based on the Karhunen–Loève linear …

Steganography is a science dealing with writing hidden messages in a specific way that only
the sender and the intended recipient are able to decipher. Important domains, besides …

Digital watermarking has been identified as a major technology to achieve copy control and
ownership protection, due to improvements in imaging technologies and the ease with …

In this paper a fragile watermarking technique based on Karhunen-Loève transform (KLT)
and genetic algorithms (GA) is proposed. To achieve high sensibility to content …

Digital watermarking is a technique used against illicit distribution of copyrighted material. In
this paper we present steganographic techniques for watermarking, with an emphasis on …

Steganography is a science that focuses on concealing messages using specialized
techniques so that only the sender and receiver know of the message's existence and are …
