Comparison of optical character recognition software information
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)
ABBYY also supplies SDKs for embedded and mobile devices. Professional, Corporate and Site License Editions for Windows, Express Edition for Mac.[3]
