Abstract
This invention overcomes the disadvantages of the prior art by providing a system and method for reading symbology, and more typically linear barcodes ('symbols') that employs trained attributes that remain invariant between scans of different barcodes during runtime to tune various aspects of the procedure for locating and decoding such barcodes. The procedure relies upon a training step in which one or more exemplary barcodes are decoded and the invariant attributes for such barcodes, including, but not limited to, size, shape, relative angle in the image field of view and resolution are stored. The runtime decoding procedure then employs these attributes to constrain the search for subsequent, scanned barcodes and then decode it according to a plurality of tuned steps.
