How to get OCR accuracy result

Post by cuongb » Tue Dec 04, 2012 9:38 am

I would like to retrieve OCR accuracy result (70%, 80%, ...) as well as the position of unrecognized character after doing OCR with TIF/PDF. How can I do in GdPicture9.NET ?

Hi,

For the confidence please see:

As for the position of the character, you need to use the OCRTesseractGetCharLeft OCRTesseractGetCharTop functions:

Best,
