  • Publication number: 20200242397
    Abstract: When there is an image component common to multiple registered images, the accuracy of individual identification lowers. A decision unit decides, for each partial area, the degree of effectiveness relating to calculation of a score representing a similarity between a registered image obtained by capturing an object to be registered and a collated image obtained by capturing an object to be collated, based on whether or not the partial area contains an image component common to multiple registered images obtained by capturing multiple objects to be registered. A calculation unit calculates the score based on image components contained in the registered image and the collated image and on the degrees of effectiveness.

  • Publication number: 20200019810
    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.
