Hi Shree, just a quick update. I've now looked into this output tesseract.log further and now understand how it works and how it will go through different choices and eventually decides on a "best choice". However the output doesn't explain how it then decides what has overriding priority on giving the best outcome. The fact that even after it scours through the "fo" dictionary, it decides on best choice for this dictionary, immediately it will move onto eng dictionary and seems to decide to use eng dictionary output because (i'm guessing), it regards it as more accurate. This means your theory about our custom "fo" dictionary not being trained to a high enough accuracy level seems to be correct. Is there any possible way i can train either eng or fo to improve it's accuracy or override another dictionary on specific characters it's getting wrong? for example, in our case, the eng.traneddata dictionary sometimes gets 3's and 5's mixed up and it has a lot of trouble with 4's.
Your help on this would be greatly appreciated!
