godrone Optical Flow

We need to implement the optical flow algorithm for the bottom camera to avoid the drone drifting over time. Ideally I'd like to get an understanding of the underlaying math and implement this in Go, but for now a binding to something like OpenCV may also be fine (even so I'd prefer to use a more lightweight library, I recall seeing a cool looking pure C lib at some point).

This will require #8 first.

If you were thinking about http://libccv.org/ , it does not implement Optical Flow.

Yes, that's the one I was thinking off. Bummer about it not supporting optical flow. I guess we'll have to go with another library, or implement optical flow ourselves :wink: . Btw. are you online in Skype / IRC right now?

no time right now. https://github.com/inspirit/jsfeat/blob/master/src/jsfeat_optical_flow_lk.js looks portable.

Yup, looks doable. Just don't make a typo :)
