Tess 3.01 By trial and error, I seem to have found the following limitation:
No single line may contain all-caps (ignoring punctuation). If it does, tess will blow up your model and give you incorrect upper and lower case output. There is no warning. At first, I was finding trouble just with the ALL CAPS title, but now I find that there were other places in the training input that had an ALL CAPS line, and it appears to be the source of much chaos. It would be nice to have a warning when it is about to screw up your model. In another case, it was rare to have a capital O, but I had 54 small o's in training already. When I added this line with a single O instance, suddenly all the ocr was outputting was capital O's: Ologón ó! When I found that I was able to correct it by adding more of the line: "Ologón ó!" arsa an fear. Then it was working just fine. I want to have a warning when Tess is about to go psychotic. Even better real rules of what you must avoid. Why is it ignoring the character in the box file? It sure knows fromt he unicharset that the character is upper-case. Even using -psm 6 does not solve this madness. I want to avoid these training land-mines, but I don't even know what the rules are.
