In the originally published version of this paper the affiliation of the first author, The Nham Luong, contained a punctuation mistake due to which the city was incorrectly stated as “Chi Minh City” instead of “Ho Chi Minh City”. The affiliation of the authors Christophe Marquesuzàa, Patrick Etcheverry, Thierry Nodenot, and Sébastien Laborie was incorrectly stated as “T2i – LIUPPA, Université de Pau et des Pays de l’Adour, 2 Allée du Parc Montaury, 64600 Anglet, France”. This has been corrected.
