LEADTOOLS OMR SDK Module
Optical Mark Recognition for Scanned Documents
OMR programming is supported in an API and COM interface and coming soon, .NET.

The LEADTOOLS OMR module is used for recognizing optical marks (checkmarks). Typical applications include the processing of questionnaires, ballots, educational tests and reporting, and ordering sheets, where the documents to be processed are form-like and filled in by hand by respondents.

The OMR features are included as an add-on module to extend the functionality of the LEADTOOLS Document Imaging Suite and the LEADTOOLS OCR Module by providing properties, methods, and events for easily incorporating the ScanSoft SDK 12 Pro engine into your applications.

The following screen shot shows the options for OMR recognition modules:

The frame for the mark can be a rectangle, a hexagon, a circle, or an ellipse and can be filled in by any method (x, tick, hatching, horizontal or vertical lines, etc.). The frame may be visible or invisible (scanner dropout) in the image sent for recognition.

OMR Benchmarks

Recognition accuracy is 99.95% and the average recognition time is 0.005 seconds per checkbox zone (measured on a computer with 166 MHz Pentium Processor / 16 MB RAM).
