1. An information processing device comprising one or more processors, wherein the one or more processors function as a plurality of units comprising:
(1) a detecting unit configured to detect a crack region using a local feature extracted from each of positions in an input image obtained by image capturing of a structure;
(2) a deriving unit configured to derive a line component indicating positions of a plurality of cracks by thinning the crack region;
(3) a specifying unit configured to individually specify the plurality of cracks by deriving a line component indicating a position of an individual crack of the plurality of cracks by dividing the line component indicating positions of the plurality of cracks in accordance with changes in direction of the line component indicating positions of the plurality of cracks;
(4) an extracting unit configured to extract a feature pertaining to a partial image of a defect from the input image, on the basis of the specified plurality of cracks; and
(5) an attribute determining unit configured to determine an attribute of the defect using the feature pertaining to the partial image of the defect.
