  • Publication number: 20050201639
    Abstract: A scannable form, and a method and system of use which incorporates digitally encoded symbols which have identifiable centers that act as control points to permit a digital image to be aligned with a template containing the same control points. The digital encoding permits identification of the type of form and the spatial arrangement of the symbols permits alignment of the form with the template. Preferably, the digital symbols are geometrically symmetrical and the identifiable centers are centroids. Recognition of any three centroids is sufficient to allow the system to calculate transformation parameters to realign the image. Due to the geometrical symmetry, error correction is possible if any of the symbols are incorrectly identified.
