Abstract
To precisely extract a static feature value from consecutive images taken in a dynamic environment that is crowded by many people. A feature value extraction apparatus includes: a consecutive-image acquisition unit configured to acquire consecutive images that are consecutively taken; a local feature value extraction unit configured to extract a local feature value at each feature point from the consecutive images; a feature value matching unit configured to perform matching between the consecutive input images for the local feature value extracted by the local feature value extraction unit; and an invariant feature value calculation unit configured to acquire, in the local feature values for which matching between a predetermined number of consecutive images has been obtained by the feature value matching unit, an average of the local feature values whose position changes between the consecutive images are equal to or less than a predetermined threshold value as invariant feature value.
