Claim One:
1. A method comprising: receiving, by an image processor, an image including a plurality of items; identifying, by the image processor, each item in the image; generating, by the image processor, a region of interest for each identified item in the image; determining, by the image processor, a dimension of the region of interest for each identified item in the image, wherein the dimension of the region of interest is expressed in pixels; determining, by the image processor, whether one of the identified items in the image is a reference marker with a stored physical dimension; responsive to one of the identified items in the image being the reference marker, determining, by the pixel-to-physical dimension ratio engine, a pixel-to-physical dimension ratio using the dimension of the region of interest of the reference marker and the stored physical dimension of the reference marker; and determining, by a size engine, a stock keeping unit identifier of each identified item in the image based on the pixel-to-physical dimension ratio and the dimension of the region of interest of each identified item.
