I wonder if someone has tried to dewarp whole book from a video when flipping through it. I imagine that could be handy way to copy the whole book.

- mortenjorck 10y agoPage warp becomes but a tiny part of the problem with a page-flip video – now you have motion blur, varying exposure, resolution, noise, and depth of field to worry about. Maybe if you had a camera capable of recording extremely high frame rates at high resolution (probably north of 120fps @ 1440p), a high-intensity, diffuse light source, and a lens with a tight aperture / narrow focal length, you’d at least have something to work with.
- voxic11 10y agoDoesn't that describe most modern cell phone cameras?
- Jarwain 10y agoI haven't heard of a phone camera that can do video at 120fps, they're usually 30, maybe 60 fps. The S7 has some high framerate slow-mo option, but it's limited to a 720p resolution.
- chrisfosterelli 10y agoThe iPhone 6S records 1080p at 120 fps and 720p at 240 fps for their Slow-Mo feature [0]. [0]: http://www.apple.com/ca/iphone-6s/specs/ http://www.apple.com/ca/iphone-6s/specs/
- loeg 10y agoThe iphone 6S can do 120 fps for a short period of time.
