Abstract
Selon certains aspects, la présente invention concerne des procédés pour générer une carte thermique comprenant une pluralité de points d'échantillonnage ayant une pluralité de valeurs caractéristiques associées à la lumière non visible détectée, identifier un ou plusieurs macro-blocs comprenant chacun un sous-ensemble de la pluralité de points d'échantillonnage, calculer un nombre d'occurrences de la valeur de motif local à l'intérieur de chaque sous-ensemble de la pluralité des points d'échantillonnage pour chacun du ou des macro-blocs, générer un premier réseau comprenant une pluralité de valeurs pondérées par calcul de la pluralité de valeurs pondérées sur la base des nombres d'occurrences de la valeur de motif local et de tailles correspondantes du ou des macro-blocs, affecter un indice unique à chacune de la pluralité de valeurs pondérées, générer un deuxième réseau de l'indice unique par classement de la pluralité de valeurs pondérées, et générer un troisième réseau comprenant une pluralité de distances de classement.
