Description
The engine(s) used for OCR recognition:
Type
Description
ievOCRLegacy
Uses the older engine (from IEVision 4.5.2 and older)
ievOCRLTSM
Uses the new LTSM OCR engine (faster and more accurate than Legacy)
ievOCRLTSMAndLegacy
Uses either LTSM or Legacy
ievOCRDefault
Uses LTSM if newer TrainedData files are available, otherwise falls back to Legacy
Generally, this should remain as ievOCRDefault, which uses the engine available. Do NOT use ievOCRLegacy or ievOCRLTSMAndLegacy unless you are using the legacy engine files.
