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)

Evaluation

A 2016 analysis of the accuracy and reliability of the OCR packages Google Docs OCR, Tesseract, ABBYY FineReader, and Transym, employing a dataset including 1227 images from 15 different categories concluded Google Docs OCR and ABBYY to be performing better than others.
