Claim:
1. An object discriminating apparatus comprising: one or more processors; and a memory coupled to the one or more processors, the memory having stored thereon instructions which, when executed by the one or more processors, cause the apparatus to: obtain an input image including an object; extract a feature from the input image; calculate, by collating the feature extracted from the input image with a feature of a previously registered registration image, similarity between the object included in the input image and an object included in the registration image; acquire a magnitude of a variation of the input image and a magnitude of a variation of the registration image; calculate a value of a difference between the magnitude of the variation of the input image and the magnitude of the variation of the registration image; select a conversion model corresponding to the value of the difference from a plurality of conversion models; convert the calculated similarity using the selected conversion model; and determine, on the basis of the converted similarity, whether or not the object included in the input image is identical with the object included in the registration image.
