A two-stage pipeline includes a first stage that is a static filter applied to an inverse perspective mapping (IPM) image. A SLAT (Symmetrical Local Adaptive Threshold) method, according to some embodiments, is more adaptive to environment changes. Additional geometry restrictions in the static filter remove clutter. The second stage of the pipeline is a dynamic filter. The motion of blobs is analyzed to find regions that look and behave like road marking.
