Example of Results from the
ESPRIT VIEWS Traffic Understanding System


Three-dimensional models of vehicles may be used to "explain" images of traffic scenes.

The computer knows where the camera is in relation to the ground and searches for instances of vehicles (the class of the vehicle and its position on the ground) which match the edge data in the image.

Once a vehicle is recognised, it can be tracked through long sequences of video, independently of rotations and occlusions by known structures.
