Abstract
(EN)
A template matching processing device includes: first calculation means (441) for calculating a plurality of correlation values indicating the correlation between an inputted detection image (61) and a predetermined template image (62) for each pixel unit while shifting the template image with respect to the detection image in pixel unit; and second calculation means (442, 443) for calculation coordinate position of the detection image according to the coordinate position of the center of gravity of the correlation values.
(FR)
La présente invention concerne un dispositif de traitement de concordance de modèles qui comprend : un premier moyen de calcul (441) permettant de calculer une pluralité de valeurs de corrélation indiquant la corrélation entre une image de détection entrée (61) et une image de modèle prédéterminée (62) pour chaque unité de pixel, lors du décalage de l'image du modèle relativement à l'image de détection de l'unité de pixel, ainsi qu'un second moyen de calcul (442, 443) permettant de calculer la position des coordonnées de calcul de l'image de détection en fonction de la position des coordonnées du centre de gravité des valeurs de corrélation.
(JA)
 テンプレートマッチング処理装置は、入力される検出画像(61)と所定のテンプレート画像(62)との相関関係を示す相関値を、検出画像に対してテンプレート画像を画素単位でずらしつつ、画素単位毎に複数算出する第1算出手段(441)と、複数の相関値の重心の座標位置に基づいて、検出画像の座標位置を算出する第2算出手段(442、443)とを備える。
