摘要： A produce recognition system and method which uses weighted rankings to increase the possibility that candidate identifications for a produce item will appear in the first-displayed screen of candidate identifications, rather than later screens accessed through operator scrolling. The system in includes a produce data collector which collects produce data for a produce item, and a computer system which compares the produce data to reference produce data to obtain a list of candidate identifications with first rankings based upon probability of match, determining weights for the candidate identifications based upon numbers of times the candidate identifications were correct identifications and were displayed in predetermined operator selection screen locations during past recognition events, applies the weights to the candidate identifications to obtain second rankings, displays the candidate identifications in order of the second rankings, and records an operator selection of one of the candidate identifications.
