Opticality

Congratulations on your 100th post Bob, I guess that makes you a special person ;)

Pretty much anything would zip along on a 1.7Ghz machine... i really need to upgrade!

You should be able to pickup a very cheap version of VC6 now, since MS' latest compiler is out...

It's a very helpful page describing the technique you've put up. Nice work. Have you noticed any significant behavioural improvements in the little Rodney thanks to this?

I guess 100 posts makes me an old timer.

At the moment the optical flow estimation isn't integrated with the rest of the robot - it's just a standalone demo. But potentially this sort of information could be very useful not only for categorising different types of movement but also possibly for estimating the shapes of objects.

I did read a paper recently where they had used stereo optical flow information to reconstruct partial 3D models. http://www.ri.cmu.edu/projects/project_464.html

I think it should be fairly easy to reproduce the Cog head nodding experiment using a combination of skin tone recognition and optical flow. It might also be possible to have the robot exhibit a startle response if an object is moved quickly towards the cameras, which produces a "star field" type of flow pattern.
