I see.
However there are only 4 OEM parameters I can find in tess-two sorce code :
@IntDef({OEM_TESSERACT_ONLY, OEM_CUBE_ONLY,
OEM_TESSERACT_CUBE_COMBINED, OEM_DEFAULT})
public @interface OcrEngineMode {}
/** Run Tesseract only - fastest */
public static final int OEM_TESSERACT_ONLY = 0;
/** Run Cube only - better accuracy, but slower */
@Deprecated
public static final int OEM_CUBE_ONLY = 1;
/** Run both and combine results - best accuracy */
@Deprecated
public static final int OEM_TESSERACT_CUBE_COMBINED = 2;
/** Default OCR engine mode. */
public static final int OEM_DEFAULT = 3;
I sincerely can not find a suitable OEM parameter. I don't think there is
any other OEM parameter in tess-two.
(Again, the version I use is https://github.com/alexcohn/tess-two

, 9.0.0)
Could you please give me some more tips.
