PyTesseract - recognize digits in simple image
0
I'm trying to use pytesseract to recognize two numbers from an image:
- I have tried
--psm 6up to10
- I have tried
-c tessedit_char_whitelist=0123456789'
None of the above returns 49 number. Closest I got is returned 4 without 9
Do you have any tips about how to make tesseract recognize it ?
python ocr tesseract pytesseract

Have you tried different --oem ? I would also try to use a --psm higher than 10.

Try --psm 13 --oem 3 (oem = 1 or 2 should do also)
import pytesseract
from PIL import Image
import requests
import io
response = requests.get('https://i.stack.imgur.com/oAAXR.png')
text = pytesseract.image_to_string(Image.open(io.BytesIO(response.content)), lang='eng',
config='--psm 13 --oem 3 -c tessedit_char_whitelist=0123456789')
print(text)
yields 49 as you expect on my machine.
I get the same result by downloading the image locally and firing
tesseract oAAXR.png output --oem 3 --psm 13 -l eng
For reference my tesseract --version gives
tesseract 4.0.0 leptonica-1.77.0 libgif 5.1.4 : libjpeg 8d (libjpeg-turbo 2.0.1) : libpng 1.6.36 : libtiff 4.0.10 : zlib 1.2.11 : libwebp 1.0.1 Found AVX2 Found AVX Found SSE.

Where is --psm 13 documented? I only see 1-10 here: TESSERACT(1) Manual Page.

Aw, looks like their documentation may be inconsistent or refers to different versions there, check github.com/tesseract-ocr/tesseract/wiki/Command-Line-Usage for psm > 10.

Thanks for the answer, but your code gives me "ay" string instead of 49. tesseract versions: tesseract 4.0.0 leptonica-1.77.0 libgif 5.1.4 : libjpeg 9c : libpng 1.6.36 : libtiff 4.0.10 : zlib 1.2.11 : libwebp 1.0.1 : libopenjp2 2.3.0 Found AVX2 Found AVX Found SSE I'm also using MacOS (Mojave). Maybe that has something to do with it

Yeah I can see that only difference is: your libjpeg is 8d and my libjpeg 9c. Everything else is same.
