• it's purpose is to do one thing, and to do it right
• lightweight (no heavy models), fast and super-easy to use
• the code detects pixels that are supposed to be white and makes them white, so that if you need to print the document you don't have to waste ink
• automatically scan all the images in a directory
• choose if you want the result to be colorized or black and white

The photo must contain the 4 corners of the sheet (it will obviously work better if there's nothing else in the picture and if the quality is high), and it has to be vertical.

git clone https://github.com/davide710/scanner.git
pip install -r requirements.txt

python3 scanner.py path/to/image [-c (colorized)]

python3 scanner.py path/to/folder [-c (colorized)]

python3 scanner.py . [-c (colorized)]

If for some reason the sheet isn't detected, run the other script (replace scanner.py with doc_scan_click.py). This time the image will appear and you'll be clicking on the 4 corners of the document

I keep uploading many results, trying to show both examples of successful and failed tests and highlight pros and cons of the different ideas I get. If you want to improve this, if you have an idea to make it better, or if you are having trouble using or setting this up, please raise an issue. Otherwise, work on one of the improvements I mentioned in the Issues section. You can also star the repository.
