Digitizing photos of whiteboards using the command line

Looks much better than the original photos. On a slightly related note, camscanner, an app for android (and IOS?) does something similar, but can also correct for the angle at…

very nice, never experimented with modifying images via command line but was able to understand the process via shell parameters. also photos of whiteboards always come out…

Great work, thanks heaps for this! This'll help me clean up files quickly and easily, as we do the same thing a lot of the time too :) NB: This works fine on the Windows version…

Nice. Works well for drawings/comics. http://imgur.com/a/Xvu7K

Awesome, thanks!

I got excited when i saw the results since they looked awesome, such that I thought I could replace my quick&dirty transparent GIFs script[1], but apparently it has issues with…

Nice idea, would it be possible to do some OCR at the end?

I'd like to see similar script for blackboards (greenboards?).

For those of you who would like to use this on smaller images, play around with "DoG:15,100,0". This string refers to implementing a difference of gaussian filter with inner…

I'm doing an online whiteboard (spacedeck.com) and always wondering how to bridge the analog/physical world of whiteboard scribbles and sticky notes and software. How would you…

There's a whole heap of iOS 'scanning' apps that do this sort of thing device-side.

Or Android.

Take a look at unpaper instead. It was designed for postprocessing scanned documents. The only thing it does not do is the Evernote upload: https://github.com/Flameeyes/unpaper

Take a look at Tesseract, which last time I looked was the best codebase to use in this area. It's part of Google's open source multilingual OCR suite, which is in two parts…
