OcrEngineMode Enumeration
When Tesseract/LSTM is initialized we can choose to instantiate/load/run only the Tesseract part, only the Cube part or both along with the combiner. The preference of which engine to use is stored in tessedit_ocr_engine_mode.

Namespace: Emgu.CV.OCR
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: (
public enum OcrEngineMode
  Member nameValueDescription
TesseractOnly0 Run Tesseract only - fastest
LstmOnly1 Run just the LSTM line recognizer.
TesseractLstmCombined2 Run the LSTM recognizer, but allow fallback to Tesseract when things get difficult.
Default3 Specify this mode when calling init_*(), to indicate that any of the above modes should be automatically inferred from the variables in the language-specific config, command-line configs, or if not specified in any of the above should be set to the default OEM_TESSERACT_ONLY.
