Nice! It could be used before feeding a OCR

  Wonder how close this is to the techniques apps like Office Lens use. I am always amazed to the extreme angles I can take a photo and the app still makes it end up as perfect pdf.

      Sure. This wasn’t an advocacy for any tool. I suppose most tools use similar tricks and was wondering if it was anything like the one presented here.

I can't seem to find the link now, but there was a post here a couple of weeks back about someone doing a very similar thing (in Python, IIRC) to clean up pictures of handwritten notes. It seemed conceptually simple, and worked quite nicely.
