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 frame for the mark can be rectangular, hexagonal, circular or elliptical 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. Requires either LEADTOOLS Document Imaging SDK, LEADTOOLS Medical Imaging SDK or the LEADTOOLS OCR Module.
