In an article handling system that functions to make article discrimination-identification determinations, the possible article orientations are stored and compared (Step 116, Fig. 2) to establish maximum pixel difference numbers and identification of the longitudinal window position along the article where such maximum difference occurs (Steps 118, 120 Fig. 2). Each of the possible orientations is compared with all other possible orientations (loops A. B. Fig. 2) so that a small number of windows is identified as part of a setting-up procedure. When operating, the work articles are scanned and only the data at window locations are used to make article orientation identification, thus reducing the time and memory requirements for data processing. The time and memory may be further reduced by compacting each scan by only storing count values relating to edge locations. <IMAGE> |
