要約
(EN)
An object recognition device includes an image input unit, an object dictionary unit, and a processing unit. The image input unit acquires image data. The object dictionary unit stores an object condition for identifying the object type according to the hierarchical structure of the object type. The processing unit successively correlates the object condition according to the hierarchy so as to narrow the object conditions to be correlated and identify the object type captured in the image data.
(FR)
L'invention concerne un dispositif de reconnaissance d'objet comprenant une unité d'entrée d'image, une unité de dictionnaire d'objet et une unité de traitement. L'unité d'entrée d'image acquiert des données d'image. L'unité de dictionnaire d'objet stocke une condition d'objet pour identifier le type d'objet selon la structure hiérarchique du type d'objet. L'unité de traitement met en corrélation de manière successive la condition d'objet selon la hiérarchie, de façon à resserrer les conditions d'objet à corréler et identifier le type d'objet capté dans les données d'image.
(JA)
 被写体認識装置は、画像入力部と、被写体辞書部と、処理部とを備える。画像入力部は、画像データを取り込む。被写体辞書部は、被写体種類を特定するための被写体条件を被写体種類の階層構造に従って記憶する。処理部は、階層に従って被写体条件の照合を順次行うことで、照合する被写体条件を絞り込みつつ、画像データに写っている被写体種類を特定する。
