1. An apparatus to manage a database for object recognition, the apparatus comprising:

  • a detector to determine a first likelihood of detection for a reference shape at a first distance from an image capturing device;

    a grouper to store the reference shape in a first group of a plurality of groups of reference shapes in the database based on a comparison of the first likelihood of detection with a first threshold, the first group associated with the first distance;

    a calculator to aggregate a plurality of depth values associated with an object outline in an image to determine a combined depth value associated with the detected object outline; and

    a comparator to limit comparison of the object outline in the image to reference shapes of the first group responsive to the combined depth value corresponding to the first distance.
