ABSTRACT:
A system and method of detecting a barcode involves obtaining a two-dimensional source image and converting it into a frequency domain image (FDI). Frequency trends in the FDI are then analyzed to determine whether barcode information is present in the FDI. In this way, the presence, location, orientation, size and symbology of a barcode can be quickly and accurately determined.
