Abstract
The disclosure includes a system and method for distinguishing between stock keeping units of similar appearance that vary in size. An image recognition application receives an image depicting a plurality of items, identifies each item in the image, generates a region of interest for each identified item in the image, determines a pixel dimension of the region of interest for each identified item, determines whether one of the identified items in the image is a reference marker with a stored physical dimension, determines a pixel-to-physical dimension ratio for the reference marker using the dimension in pixels and stored physical dimension of the reference marker, and determines a stock keeping unit identifier of each identified item in the image based on the pixel-to-physical dimension ratio and the pixel dimension of the region of interest for each identified item.
