As the Internet becomes more and more populous, people concern more about the copyright protection issue for digital data such as images and audio. Digital watermarking technique can hide data in images or audio to indicate the data owner or recipient. Therefore, it can protect the copyright. There were a lot of papers discussing how to embed watermark into images in recent years. However, few ...

In this paper, we determine the watermark domain that maximizes data hiding capacity. We focus on the situation in which the watermarked signal undergoes lossy compression involving quantization in a specified compression domain. A novel linear model for the process of quantization is proposed which leads to analytical results estimating the data hiding capacity for various watermarking domains...

We derive capacity bounds for watermarking and data hiding in the presence of JND perceptual coding for a class of techniques that do not suffer from host signal interference. By modeling the lossy compression distortions on the hidden data using non-Gaussian statistics, we demonstrate that binary antipodal channel codes achieve capacity. It is shown that the data hiding capacity is at most equ...

In this paper, we derive a theoretical capacity for digital image watermarking with zero transmission errors. We present three di erent discrete memoryless channel models to represent the watermarking process. Given the magnitude bound of noise set by applications and the acceptable watermark magnitude determined by the just-noticeable distortion, we estimate the zero-error capacity by applying...

Reversible watermarking techniques enable the extraction of the embedding bits from a watermarked image in a lossless way. It exploits the high spatial correlation among neighboring pixels. Application in reversible watermarking includes military and medical images. However, images occurs overflow or underflow problems during the imbedding process. Since pixels value may be out of range between...
