Data Extraction From PDFs Containing OCR image.

I have a PDF , in Page 2 there is a table containing an image …I want to get that table as output in excel/Gsheet. Can Somebody help me here? I am trying using Image Reader and Tess4J nodes but not making any progress.

Hi @Mayank_2611 and welcome to the forum.

This is a question that comes up now and then. Take a look a this post, maybe it can work as a starting point:

I went ahead and removed the PDF example file you uploaded since it contains personal information (names and addresses).

First step with two ways:

  1. I’m using Tikka node with embedded pictures saved to a particular folder (not running with the lastest versions of PDF with new format of embedded pictures encoding).
  2. I’m using a external open source and free library (poppler) to convert PDF pages into pictures saved to a particular folder.

From this folder, I create images and use Tess4J to make the OCR of pictures.

For new encoded embedded pictures, I search external free and open source tools.
It should be great if KNIME can create a node :slight_smile:
