OCR POC

This is a simple POC for OCR reading images and documents.

The Node.js code relies on a couple of NPM packages that in turn act as wrappers around ghostscript and tesseract that perform the actual OCR processing.

TODO

• Change to node lts
• Cleanup the Dockerfile
• Swe language in PDF processing
• Investigate PDF processing performance

Setup

brew install ghostscript tesseract tesseract-lang
nvm install && nvm use
npm ci

Run

# Set TESSDATA_PREFIX (MacOS + brew)
export TESSDATA_PREFIX=/opt/homebrew/share/tessdata

npx nodemon

Add more images/documents to the input/ dir to try it out.
