Claim One:
1. An apparatus, comprising: a reference comparator to: compare a first reference region of a first reference image stored in a database with a first region of a first image to determine a first match value, the first region corresponding spatially to the first reference region; in response to determining the first match value satisfies a first threshold, compare a second reference region of the first reference image with a second region of the first image to determine a second match value, the second region corresponding spatially to the second reference region; and in response to determining the second match value satisfies a second threshold, associate the first image with a product associated with the first reference image, the product being associated with a plurality of second reference images stored in the database; and a reference image manager to, in response to determining the second match value satisfies the second threshold: decrement second index values associated with ones of the second reference images; and remove a reference record associated with one of the second reference images from the database based on a corresponding one of the second index values satisfying a first condition, the removal of the reference record reducing the storage space required to store reference records in the database, at least one of the reference comparator or the reference image manager including hardware.
