csron / slide-pipe

Take photos of slides, pipe them to your computer and paste them well formatted to your current notes.

slide-pipe

Pipe slides you are photographing from a conference / presentation / whatever with your phone directly to your computer clipboard. The pipe not only creates a "shared clipboard" but also pre-processes the image to only get the slide and not all conference participants. Here is an example from some of Uncle Bob Martins youtube videos (https://www.youtube.com/watch?v=o_TH-Y78tt4). The input image is the left and the green one gets extracted and piped to the clipboard:

Prerequisites

• You need a shared folder between your phone and your computer. I have my own NAS with a WebDAV server running mounted on my computer. Photos are synced automatically to the NAS.

• Create and start a virtual environment

  python3 -m venv .venv

  source .venv/bin/activate

• Install Requirements

  pip install -r requirements.txt

• On Ubuntu install xclips

  sudo apt install xclip

Getting started

• Start the pipe

  python3 slide_pipe.py /PATH/TO/SHARED/FOLDER

Limitations

• The OpenCV pipeline is currently only suited for 16:9 slides with white background.
• Tested with Ubuntu22.04

ToDos / Ideas

• Couple the pipe with OCR and extract the text
• Give the text to a custom GPT and extract important notes directy
  • give equations in Latex

Notes

The project idea came sitting in a conference taking notes and thought it would be incredible to be able to pipe the slides directly to my computer clipboard.
