Abstract

L'invention concerne un procédé destiné à actionner un ordinateur de détection de fumée et de flammes qui consiste : à recevoir des images numérisées d'une région à surveiller, à comparer les pixels d'une de ces images avec les pixels d'une autre image selon deux procédures prédéterminées, afin de produire une décision de présence de flammes et une décision de présence de fumée, et à fournir un signal d'incendie détecté en fonction des décisions de présence de fumée et de flammes.
