Page Scan Corrector
Utility for using opencv to detect and reformat page scans, as for OCR.
The program will attempt to crop an image (PNG, JPG) to only major text sections. Preserves color.
Installation
Prerequisites
You'll need to install OpenCV on your platform. This does not require a bleeding-edge version, so using a package manager version should work (e.g. brew install opencv on a Mac).
pipenv install
setup.py install --editable .
Running from the command-line
process_image input.png outdir
This will write outdir/input.png with the result.
