This paper presents a security analysis for data hiding methods based on nested lattice codes, extending the analysis provided by previous works to a more general scenario. The se...
Presentation
The Discrete Pascal Transform (DPT) has been proved remarkably useful for edge detection, filter design, discrete-time signal interpolation and data hiding. In the present work a n...
