Data Extraction From PDFs Containing OCR image.

KNIME Analytics Platform
3

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:
