In the original version of this Review Article the affiliation and address for Lorenzo Rosa were incorrectly given as “University of Parma, Department of Information Engineering, Parma 43121, Italy”.

These have now been corrected to “University of Modena and Reggio Emilia, Department of Engineering “Enzo Ferrari”, via Vivarelli 10, I-41125 Modena, Italy” in the HTML and PDF versions.
