Abstract
During operation of a vending machine, visual images of the next product to be dispensed from product dispensing locations are obtained. Features of the visual images are compared to a data base of features to determine the identity of the next product to be dispensed from each of the dispensing locations. After a product has been dispensed from a dispensing location, a visual image is obtained of the next product at the dispensing location. Features of the visual image of the next product at the dispensing location are compared to a data base of features to determine the identity of the next product to be dispensed. A displayed price of a product is compared with product prices in the data base. If necessary, the displayed price is adjusted to agree with the data base.
