Hi, I'm training tesseract on my own dataset which only contains digits, comma, and period.

During training phase, the printed output displays at most 3 lines for each text: GROUND TRUTH, ALIGNED TRUTH, BEST OCR TEXT.

The below is an example:

I'm wondering what those ALIGNED TRUTH and BEST OCR TEXT exactly mean.

The Wiki page says just " GROUND TRUTHfor the line is displayed in all cases. ALIGNED TRUTH and BEST OCR TEXT are displayed only when different from the GROUND TRUTH. "

Is there anyone who know what they are?

Thank you for your reply in advanced.

Thank you for your kind reply, Ashwini.

Yeah, I totally agree with your mention.

And, could you tell me what the ALIGNED TRUTH is?
