A Stochastic Approach to Content Adaptive Digital Image Watermarking
This paper presents a new stochastic approach which can be applied with different watermark techniques. The approach is based on the computation of a Noise Visibility Function (NVF) thatExpand

Multilevel 2-D Bar Codes: Toward High-Capacity Storage Modules for Multimedia Security and Management
In this paper, we deal with the design of high-rate multilevel 2-D bar codes for the print-and-scan channel. First, we introduce a framework for evaluating the performance limits of these codes byExpand

Text data-hiding for digital and printed documents: theoretical and practical considerations
In this paper, we propose a new theoretical framework for the data-hiding problem of digital and printed text documents. We explain how this problem can be seen as an instance of the well-knownExpand

Analysis of bit-rate definitions for Brain-Computer Interfaces
A comparison of different bit-rate definitions used in the Brain-Computer Interface (BCI) community is proposed; assumptions underlying those definitions and their limitations are discussed. CapacityExpand
