A method of location and identification of an object of interest in a complex image frame involves defining the object of interest as a reference template. The ranks of grey shades in the complex image frame and reference template are computed (17). The rank of grey shades in the reference template are compared with the ranks of grey shades of the complex image (18), thereby determining closeness of fit. A threshold for detection is set by utilizing selected decision data (19).

Un procédé de localisation et d'identification d'un objet à étudier dans une trame d'image complexe consiste à définir ledit objet en tant que grille de données de référence. Les étages des nuances de gris dans la trame d'image complexe et la grille de données de référence sont calculés (17). Les étages des nuances de gris dans la grille de données de référence sont comparés aux étages de nuances de gris de l'image complexe (18), ce qui permet de déterminer la précision d'adaptation. Un seuil de détection est fixé au moyen de données de décision sélectionnées (19).
