What's the technology behind Skype's anit-shake video recording? [closed]

Question

Skype added an anti-shake feature in it's video conference app on iPhone. How can that be done?

Answer 1

This is quite a complicated thing to pull off, but it's probably a combination of some powerful blur detection/removal algorithms, and the gyroscope. I would start by looking into how to detect motion with the iPhone, and see what kind of results you can get with that. If it's not enough, start looking into shift/blur direction detection algorithms. This is not a trivial problem, but is something that you could probably accomplish given enough time. Hope that Helps!
