I found the answer, thanks to this thread.
It seems that tesseract suports the uzn format (used in the unvl tests).
From the thread:
Calling tesseract with parameter "-psm 4" and renaming the uzn file
with the same name of the image seem works.
Example: If we have C:input.tif
and C:input.uzn
, we do this:
tesseract -psm 4 C:input.tif C:output
