OMR stands for Optical Mark Recognition. For more information refer to Using OMR in LEADTOOLS .NET OCR.
You can get the instance of the IOcrOmrOptions interface currently used in the engine using the IOcrSpellCheckManager.OmrOptions property.
With the IOcrOmrOptions interface, you can change the following OMR settings:
Calling IOcrPage.Recognize, updates all OMR zone properties as follows:
Property | Description |
---|---|
OcrZone.OmrState | Either OcrOmrZoneState.Filled if the mark is recognized as being filled or checked, or OcrOmrZoneState.Unfilled if the mark is recognized as being unfilled or unchecked. |
OcrZone.OmrConfidence | A number between 0 and 100 (where 100 is maximum confidence) that specifies the confidence the OCR engine has in recognizing the OcrZone.OmrState. |
The OMR zones of a page have the following properties:
Property | Value |
---|---|
OcrZone.FillMethod | Set to OcrZoneFillMethod.Omr |
OcrZone.RecognitionModule | Set to OcrZoneRecognitionModule.Omr |
All LEADTOOLS OCR engines support OMR. However, currently autodetection of OMR zones is not supported. Instead, you need to: here is no current support for auto-detecting OMR zones in a page, you have to add the OMR zones manually to the page by setting their boundary (through OcrZone.Bounds, the fill method and recognition module as described above and adding the zone to the page using the IOcrPage.Zones collection before calling IOcrPage.Recognize.
To use OMR in LEADTOOLS, you need a special key to unlock the OMR capabilities. For more information, refer to Unlocking Special LEAD Features.
