Our Open Recognition Toolkit (OpenRTK) 6.0 is a C/C++ toolkit that provides an innovative solution to application developers, system integrators and OEM customers who need to integrate OCR capability into their applications with minimum engineering efforts.

The OpenRTK is based on ExperVision's proprietary MLFA (Machine Learned Fragment Analysis) technology, which took more than 100 man-years to develop and refine. It is the core OCR Engine of our award-winning software TypeReader Professional/Enterprise. 

The OpenRTK consists of a recognition database (RTK.DB) that was built upon 8 million character samples collected from real world documents and 2,618 training fonts, dictionaries for 10 languages, and a run-time library (RTK.DLL) which contains more than 100 APIs that are well-defined for easy integration.

The "Open" concept makes ExperVision's OCR enabling technology more accessible to application developers or system integrators, giving them a competitive advantage over any other competitor's SDK.

To write your first OpenRTK application, you will need:

1. OpenRTK 6.0. It includes RTK.H, RTK.LIB, RTK.DLL, RTK.DB and GENERAL.
   * If you haven't bought OpenRTK yet and want to have a review, please contact our sales person directly. You may need to sign some pre-purchase agreements.
   
   
2. Microsoft Visual® C++ 6.0 or above. Basic VC programming skill is required. If you are not familiar with VC, please refer to corresponding VC documentation first, and then start this tutorial.
