J'ai une image FLIR dont je veux extraire la "valeur spot". La valeur du point est imprimée sur l'image. J'ai trouvé le paquet Thermimage que j'utilise dans R.Extraction de la valeur spot de l'image thermique
C'est ce que je reçois quand je lance ceci:
library(Thermimage)
flirsettings("FLIR8655.jpg", exiftoolpath = "installed", camvals = "")

Y at-il un moyen d'obtenir la mesure à savoir la valeur spot de l'image? Ou puis-je utiliser exiftool pour extraire cette valeur de l'image et comment puis-je faire cela?
