We are trying to extract text content from normal pdf and scanned pdf
(image) using tesseract-ocr.
We have observed following issues for the pdf's with table as table
Contents are not getting extracted properly.
1. Contents from few cells(rows/columns) are not visible.Sometimes
heading of the table is missing.
2. If numbers are there inside table, all the numbers are not getting
extracted.
3. Some letters are extracted wrongly . eg. i is misinterpreted as l.
4. Column sequence is getting interchanged as it is parsing horizontally.
5. Some extra characters are getting extracted along with normal one.
Tried image_to_string ,image_to_data ,opencv approach
Sample code used is:
from PIL import Image
import pytesseract from pytesseract import image_to_string from pytesseract
import image_to_boxes
image=(pytesseract.image_to_string(Image.open('table_number.jpg')))
print(image)
It should extract rows and columns properly which it is not extracting as
of now. Kindly suggest function or method to enhance the results for table
content extraction using tesseract.
