![]() The OpenRTK ® utilizes ExperVision’s exclusive MLFA technology with the ability to accurately recognize more than 2600 font types, supplemented with built-in and auxiliary (aka user) dictionaries. You can choose whether to locate pictures for better format preservation. Text regions, whether they are the result of automatic or manual Locating, can be inserted, deleted, and modified. Of course, it’s also possible to use the OpenRTK®’s built-in Locate features and then manually adjust those results. This may be useful when trying to process a form, where the location of text to be recognized on each page is always the same. Manually, defining areas of text explicitly and ignoring the OpenRTK®’s built-in Locate features.This is useful when you want to automatically process a heterogeneous set of documents where the location of text to be recognized on each page is unknown. Automatically, using the OpenRTK®’s built-in Locate features.Locating, the process of identifying and ordering the areas of text on a page, can be accomplished: Note: If you use your own image reader, it is strongly suggested that you implement scan line doubling of standard resolution images The OpenRTK ® also provides developers with APIs to detect the orientation of an image, rotate automatically if necessary, and straighten any skewed images.Each image can be read in any one of four orientations and rotated appropriately when read: Portrait, Landscape, Flipped Portrait, and Flipped Landscape.Image format supported: PCX, DCX, PDF, BMP, TIFF Uncompressed, TIFF Packbits, TIFF Group 3, TIFF Group 4, JPEG.The OpenRTK ® (SDK) can automatically read image files in the following formats and methods: ![]() If you are not familiar with VC, please refer to corresponding VC documentation first, and then start this tutorial.ġ. To write your first OpenRTK ® application, you will need: 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. DLL) which contains more than 200 APIs that are well-defined for easy integration. DB) that was built upon 8 million character samples collected from real world documents and 2,618 training fonts, dictionaries for the major Western languages and a run-time library (RTK. The OpenRTK ® consists of a recognition database (RTK. The OpenRTK ® (SDK) is based on ExperVision’s proprietary MLFA (Machine Learned Fragment Analysis) technology, which took more than 100 man-years to develop and refine. Our OpenRTK ® 7.0 (Open Recognition Toolkit ® ) 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. UNLA is registered trademarks of University of Nevada Las VegasĭOE is registered trademarks of U.S. It also provides an excellent automatic zoning capability.” It performs especially well on proportional pitch text, and is least affected by low resolution (200 dpi). It demonstrated consistently highaccuracy. “Overall, ExperVision Recognition Toolkit (the OCR engine of ExperVision) performed the best in this year’s test (among OmniPage, …and other OCR software).
