Lucas Kanade (LK) Optical Flow algorithm is now on the iPhone.
Porting OpenCVs lkdemo app to iPhone shows Optical Flow detection at real time performance! (30 FPS).
Hit "Reset" to start tracking new points.
Hit "Hud" to set many different parameters, and see how the iPhone behaves.
A must have for anyone contemplating on using the technology in there app. Great for Augmented Reality...
Enjoy!
