it would be nice to run that on GPU.

I just realized: OpenCV has functions to do all the homography hard work
already, so I'll probably use that since OpenCV is already a dependency.

Ah ok thanks! I'm surprised no one has need a linear algebra library. I
guess there's OpenCV and people use it to do the heavy lifting?
Will look into the API more.

Hello!
I want to write a more advanced video stabilizer for libavfilter (*),
implementing the algorithm described here -

The focus of the paper is rolling shutter removal, but it builds on top of
another algo
