Thanks for the video, i required some help in cropping the header and then extracting the text from the file, can you suggest how i can do that, my pdf files are a mix of scanned pdf and text pdf files

@Python2020 2 года назад

When you will read scanned pdf with pypdf2 it should throw error inside catch you can can write code for reading scanned pdf... My way

First of all, thank you for this excellent explanation, if I want to extract scanned PDF file contains complicated table to csv file, do you have any suggestions?

@Python2020 6 месяцев назад

You have to use regex and then map va values to field for a line... Then appen new line... Direct from image to csv might not be possible using these libraries

Hi. Thank you for this video.Follwoed the exact steps. For images, the code is working and output is coming as expected but for scanned pdfs, the output is generated with random alphabets and missing out a lot of text. Why is that so? what is the solution for this issue ?

@Python2020 7 месяцев назад

Quality matters

I am also getting blank .txt files for PDFs. The code is working for images. Would you mind giving a more detailed suggestion for what I should do? Thanks so much!

@Python2020 Год назад

Try to print before writing the text file... See if dara is coming in variable or not

@user-fy6gi2vx8g Год назад

@@Python2020 Thank you so much for your prompt reply! I printed the variable, and it shows up blank for all the PDF files. In one of the PDF files, I put in an image I produced by typing something in Word and then turning it into an image using Snipping Tool, so I don't think image quality is causing the problem.

@user-fy6gi2vx8g Год назад

@@Python2020 Nevermind. I discovered that I accidentally put in "5" as the page number instead of "500". I changed it to 500 and now it is working! I find this very interesting, though, because most of my PDFs are 5 pages long or shorter. Thanks so much for your help!

@CSE-AshikAhamedP Год назад

but where you trained images in Teseract OCR tools

@Python2020 Год назад

We don't have to train OCR engine.. I think You are refering to train ML models to identify right lables

Is there a possible method to extract without using the tesseract model but using py libraries only

There is a video on my RU-vid channel but it won't work for scanned pdf Or image pdf.. Only on text pdf.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7f0Bc2ateqQ.html

how can i store all the text of different pages extracted from pdf into a single text page?

@Python2020 Год назад

Use a single variable if pages are up to 10,20, once code goes out of the loop there you write the file

Hi Sir, I'm working with scanned PDFs (bank statements). The PDF quality is low, so I can't extract the text accurately. Are there any other ways to extract the text accurately?

Use Azure OCR
