Hi,
I have tesseract 3.02 on a Windows 10 PC.
I am trying to recognise text on a form scanned with a camera that has
numbers mostly in tabular form with a small amount of Hebrew characters
plus one English "graphical" word. I processed the photo to remove a pink
background pattern, and to enhance the text in the image (the original -
minus the pink pattern - produced the same results)
[image: 3198Rfat.png]
The Hebrew text on the bottom 2 lines is cut off on the right, but this
does not matter to me.
Only the numbers are of interest to me in the output.
I am running tesseract in Python using the pytesseract wrapper, and I am
running the following command:
- Imaj=Image.open(ImgPath) # ImgPath is the full path to the .png file.
- print('\n\n','v'*20,'\n',
pytesseract.image_to_string(Imaj),'\n','^'*20,'\n\n') # use eng default
I believe this corresponds to the command-line:
- tesseract ImgPath out (I used the actual path)
The output that I get is the following:
- 7547512723 2
-
- 1334718913
- 0000000000
- 3927010465.

Most of it is meaningless gibberish to me. Only the highlighted text is
recognised correctly/
When I ran it with the Hebrew language selected, it produced similar
results, but with *some *of the Hebrew characters and only the "156138"
recognised correctly.
Running tesseract manually (English) in a 'CMD' window produced the
attached file 'out.txt'.
I suspect that the font used in the form is the problem - the form was not
printed on a normal Windows, Mac or linux computer.
Which fonts were used to create heb.traineddata? Is there a way for me to
display them?
Do I have to train tesseract with the font in the form?
Any help will be appreciated!
Thanks!
