Watermarking and Multimedia Security

Presented by: Juan Ramsa Troncoso Pastoriza, Author(s): Pedro Comesaña, Fernando Pérez-González, University of Vigo, Spain

In this work Weber's law is followed for designing a perceptually-shaped side-informed data hiding scheme. The resulting method is a generalized version of a logarithmic quantization algorithm previously proposed by the authors. Closed formulas for analyzing the embedding power and decoding error probability of this new method are provided, and experimental results showing its good behavior against severe attacks are reported.
