Visual perception
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. - Bob |
