Claim One:
1. An information processing device that compares an input image while a model image, the device comprising: a storage configured to hold a feature of each of at least one model feature point on the model image and hold a feature of each of at least one model feature point on each of N (N is an integer value equal to or larger than one) transformed images that are each obtainable through transformation of the model image based on a respective one of N transformation coefficients; an object feature point extractor configured to extract at least one feature point on the input image as an object feature point; an object feature extractor configured to extract a feature of each of the at least one object feature point extracted by the feature point extractor; and a feature comparator configured to compare each of the at least one object feature point of which feature has been extracted by the object feature extractor with each of the at least one model feature point held by the storage about each of the model image and the N transformed images, and creates at least one match pair between an object feature point and a model feature point having the features that have been determined to be similar to each other through the comparison.
