A produce identification and pricing system for a supermarket checkout or other retail outlet where produce is handled includes one or more imagers which provide image data from produce to be identified, which image data includes spectral information, preferably including information from the nearer infrared as well as RGB information. The spectral information is transformed into a signature vector which is compared with target signature vectors for the variety of types of produce handled by the supermarket or other retail outlet. The best match to the target signature vectors is employed to obtain price information from a produce price database. If the produce price is based on weight, information from a scale is retrieved and the total price is calculated. If the price is based on the number of items, a count operation is enabled and the count value determined. The price is then determined based on the count value of the number of items. The total price is output to a register for computation of the total checkout price. The produce identification information is also forwarded to a database for inventory monitoring of the produce in the store. The produce identification system may be combined with a more conventional bar code scanning system at single imaging station to provide automated handling of identification and pricing of all the items at the retail outlet without requiring any additional obtrusive hardware.
