About Open Note Scanner
This little application provides a way on scanning handwritten notes and printed documents.
It automatically detect the edge of the paper over a contrastant surface.
If you have RocketBook Wave notebook or home printed pages it automatically detects the qrcode printed on the bottom right corner and scans the page immediately.
After the page is detected, it compensates any perspective from the image adjusting it to a 90 degree top view and saves it on a folder on the device.
It is also possible to launch the application from any other application that asks for a picture, just make sure that there is no default application associated with this action.
Can be also installed from F-Droid: https://goo.gl/WwB9gB
original source code and binary builds are available at: https://github.com/ctodobom/OpenNoteScanner

First of all, thank you for writing an open source image scanner! The scan quality after auto-processing is not so good, though. It would be a great app if you could fine-tune the output quality!

Works great on lg g3. Managed to capture very old handwritten papers with clarity once i had got as much light as possible and a contrasting background.

Includes setting for phoning home and was using background data. Uninstalled. Update: To send usage data? That's spyware, period. Being open source doesn't magically make this incapable of that. I'll stick to my other scanning app, thanks.

I don't want you to help with my CV, I just want to "scan" my notebook. I shouldn't need to immediately install a second app to use the core functionality of this one, what kind of developer programmed this joke? How has this spam got a 4.2 rating? Very worrying.

My dad wanted a scanner app that is easy to use. I'm a fastscanner fan but Dad found it too complicated. I tried this app and it's simple enough that even dad can use it. Turn off image processing for an actual photo.

This seemed so promising. I downloaded openCV and everything, uninstalled the F-Droid version and installed this version, put black paper behind my note to help it find it, nothing. Otherwise, it's regular features are just fine like manual mode, but it needs a crop feature.

Forces you to download an app called open note cv. No idea for what. Couldn't even use it. CS scanner is better including free batch scanning
