Abstract

Procédé d'analyse d'une caractéristique faciale d'un visage présenté (2) dans un champ d'acquisition d'un imageur (3), comprenant les étapes suivantes : - l'imageur (3) acquiert une première image d'un visage, puis acquiert une seconde image du visage, - à partir de la première image et de la seconde image, une unité de traitement détermine une variation d'une caractéristique faciale entre la première image et la seconde image, sans déterminer une valeur quantifiant un état absolu de la caractéristique faciale dans la première image et/ou dans la seconde image, - à partir de la variation de la caractéristique faciale, l'unité de traitement détermine un état du visage présenté (2) dans le champ d'acquisition d'un imageur (3) et effectue une action en fonction de l'état du visage présenté .
