pikrellcam VS OpenNoteScanner

For high performance motion detection, also check out PiKrellCam. It's a much larger project and has many more features. When comparing the video pipeline, Sentry-Picam has a better live preview but PiKrellCam has even better detection, recording, and performance.

That's been a dream of mine for a long time. I don't think there's anything quite like we want just yet.

However, there is a super cool open source project from the author of GKrellM (remember that from the ancient days of Linux?). He's using the Pi's built-in hardware video coder to get high quality motion detection very cheaply. The basic idea seems to be, when the encoder produced a lot of bits, there must have been some motion in the frame.

Came across Open Note Scanner. Last updated 2 years ago, I think, but it fits the bill.

If you can't borrow a multi-function printer at school or somewhere, try using this or this app instead of just taking photos with your phone.

You can try OpenScan or OpenNoteScanner.

Open Note Scanner - Play Store, GitHub

I've used OpenNoteScan before:

* https://f-droid.org/en/packages/com.todobom.opennotescanner/

* https://github.com/allgood/OpenNoteScanner

It works OK but it looks a bit old, and you need to install OpenCV Manager separately, outside of F-Droid for it to work.

I can deal with it, but there's no way I could ever be able to convince anybody else, especially non-tech people to use it.

This one looks like a winner in terms of UX, so I'll be using it from now on, Thank you for creating it!
