Abstract: A comparison system includes a portable terminal including image capturing unit configured to capture a comparison image of a predetermined comparison region of a comparison object; and a server including comparison unit configured to compare the comparison object with a registered object on the basis of a statistical value for the luminance value of pixels in a registered image of the registered object, the pixels of the registered image existing at pixel positions corresponding to pixel positions estimated to be generating specular reflection in the comparison image captured by the portable terminal.

Abstract: An imaging unit, an extraction unit, a feature amount pair generation unit, and an imaging parameter adjustment unit are included. The imaging unit acquires images obtained by imaging each of N (N?3) types of objects a plurality of times by setting a value of a specific imaging parameter, among a plurality of types of imaging parameters, as a certain candidate value and changing a value of the remaining imaging parameter. The extraction unit extracts a feature amount from each of the images. The feature amount pair generation unit generates, as a first feature amount pair for each of the N types of objects, a feature amount pair in which two feature amounts constituting the feature amount pair are extracted from images of objects of the same type, and generates, as a second feature amount pair for every combination of the N types of objects, a feature amount pair in which two feature amounts constituting the feature amount pair are extracted from a images of objects of the different types.

Abstract: An object management system includes an identifier generation device and an object collation device. The identifier generation device includes a generation unit that forms an ink layer on a target object, an imaging unit that images an uneven pattern on a surface of the ink layer, and a registration unit that registers the imaged result in a storage unit. The object collation device includes an imaging unit that images the uneven pattern on the surface of the ink layer formed on the target object, and a recognizing unit that recognizes the target object based on an image of the uneven pattern obtained by imaging.
