In the inventive process the morphological characteristics of point-shaped vehicle
lane markers are evaluated on the basis of a priori knowledge. For this, those
estimation processes are particularly useful, which are based on a Kalman Filter.
After the selection of suitable ROI a Matched Filter is employed, in order to better
extract from the background the image points associated with a vehicle lane marker.
The inventive process is obviously not limited to point-shaped vehicle lane markers.
