In this paper we propose a watermarking technique in the spatial domain using gray images.
Algorithms based on modulo operations are developed to embed the watermark into the …

In this paper we propose an algorithm for embedding data a into color image which uses
Increased multiple peaks histogram. The scheme does not require the knowledge of original …

In this paper, a robust lossless digital watermarking scheme based on a generalized integer
transform in spatial domain is proposed. In the proposed method, data bits are hidden into …

This paper presents a reversible or lossless watermarking algorithm for images without
using a location map in most cases. This algorithm employs prediction errors to embed data …

This paper proposes a distortionless image data hiding algorithm based on integer wavelet
transform that can hide data into the original image. The data can be retrieved and the …

In this paper, we propose a reversible watermarking algorithm where an original image can
be recovered from watermarked image data. Most watermarking algorithms cause …

Many reversible watermarking algorithms have been proposed in the literature, and all of
these solutions put emphasis on high embedding capacity with low distortion. In this paper …

Digital Watermarking is a well-known technique for digital content protection. Reversible
Watermarking techniques are a special class of watermarking techniques whereby after the …

A novel reversible data hiding scheme based on an integer transform is presented in this
paper. The invertible integer transform exploits the correlations among four pixels in a quad …

In this paper we present a reversible watermarking technique for digital images. In our
context, reversibility refers to the ability to restore the original image by the watermark …
