Abstract PROBLEM TO BE SOLVED: To provide a feature quantity extraction device capable of appropriately authenticating an object, and an authentication system.SOLUTION: A feature quantity extraction device according to the present embodiment comprises a generator, a determiner and an extractor. The generator changes a direction of an object in a first image including an image of the object such that the object faces forward on the basis of a feature point of the object detected from image data of the first image, and generates a second image obtained by changing a size of the object in the first image to a predetermined size. The determiner determines whether or not the object facing forward is present in the second image on the basis of the second image. The detector detects feature quantity of the object on the basis of the second image when the object facing forward is determined to be present in the second image.SELECTED DRAWING: Figure 1 【課題】対象物を適切に認証できる特徴量抽出装置および認証システムを提供する。【解決手段】本実施形態による特徴量抽出装置は、生成器と、決定器と、抽出器とを備える。生成器は、対象物の画像を含む第1画像の画像データから検出された対象物の特徴点に基づいて、正面を向くように第1画像中の対象物の向きを変更し、かつ、所定の大きさに第1画像中の対象物の大きさを変更した第2画像を生成する。決定器は、第2画像に基づいて、第2画像中に正面を向いた対象物が存在するか否かを決定する。検出器は、第2画像中に正面を向いた対象物が存在すると決定された場合に、第2画像に基づいて対象物の特徴量を検出する。【選択図】図1
