Realtime Optical Flow Tracking

[budusy12]

yo how do you do this it is really cool.

Hey, I think you've got something on your face.

[amidunet]

cool !

does it work if you move faster ? when does it stop to work nicely, according your velocity ?

what optical flow algorithm do you use : horn, KLT , Nagel, Anandan, .... ??

what happens if you move the camera and yourself during the tracking ?

It works when we move faster, as long as the motion blur caused by image acquisition stays low.

The flow algorithm used is TV-L1 flow, see our webpage for details.

It still works when the camera is moved, as long as the camera movement stays small (little motion blur)

What are your camera's resolution and sample rate? Does it have any influence on the accuracy of the tracking?

Thanks in advance

VGA (640x480), 30Hz, no influence on the accuracy except the evident...
