Abstract:
A feature amount acquisition device (100) includes an activation degree calculation unit (12) that derives, as an activation degree, the degree to which, in a CNN classifier (11) that has a plurality of layers and in which input data based on image data of an input image showing a first subject and a second subject around the first subject is processed in the plurality of layers to output a result of identification of the first subject, a unit of a certain layer among the plurality of layers affects the identification result; and a feature amount acquisition unit (14) that, on the basis of the derived activation degree and the image data of the input image, acquires a feature amount of the input image so that a feature amount of a low activation degree image area, which is an area of the input image corresponding to a second unit as a unit having a lower activation degree than a first unit, is smaller than a feature amount of a high activation degree image area, which is an area of the input image corresponding to the first unit.
