Comparison of optical character recognition software

This comparison of optical character recognition software includes:

  • OCR engines, that do the actual character identification
  • Layout analysis software, that divide scanned documents into zones suitable for OCR
  • Graphical interfaces to one or more OCR engines
  • Software development kits that are used to add OCR capabilities to other software (e.g. forms processing applications, document imaging management systems, e-discovery systems, records management solutions)
