Technologies

  • OpenRTK (An OCR SDK) is a C/C++ OCR Toolkit for application developers, system integrators and OEM customers who need to integrate OCR capability into their applications, e.g. DIM, FPS, other enterprise applications, embedded applications, etc.

The University of Nevada Las Vegas conducted annual tests of OCR accuracy, and between 1992-1996, the years when the OCR field was coming to maturity, and found that "Overall, ExperVision RTK performed the best in this year’s test (1994). It demonstrated consistently high accuracy. It performs especially well on proportional pitch text, and is least affected by low resolution (200 dpi). It also provides an excellent automatic zoning capability."
