Tessaract not able to output detected text

[payel roy]

Hi Team,

I am new to Tessaract. Following the code snippet. While running it, I can't get result back from Tesseract on the detect texts. Please help. 

#!/usr/bin/python

import cv2

import pytesseract

import sys

from PIL import Image

filename=sys.argv[1]

print(pytesseract.image_to_string(Image.open(filename)))

Both of the above images get detected by Amazon rekognition system with 80% confidence score. Would you please help how I can get this working on Tesseract? 

Thanks

Hi  Zdenko

Thanks for your email. I already tried with multiple combination changing different parameters. However I am still not able to get text from the image. Attached my pre-processing code, which I am running before using tesseract. But however I am unable to get text still. Please help.

IMO you miss the point. Tesseract is OCR engine with very limited text detection capability (e.g. it works fine for book scans or simple documents with minimum graphics element.

Your pictures are very complex with a lot of graphics - so you need to remove them or first run text detection algorithm and pass only text area to tesseract.

Other option is to use complex solution like google vision[1] .
