Neural networks and unsupervised feature extraction were used to classify apple images based on whether or not they included a stem or calyx end. In one experiment, the system successfully classified 98.4% of a test set consisting of 254 near-infrare

Mature 'Chester Thornless' blackberry plants were trained to the rotatable cross-arm (RCA) trellis to determine the effect of retaining two, four, or six primocanes on plant productivity. Retention of only the two oldest primocanes and generally the
