Running time:7 s
Environment:>8 cores @ 2.5 Ghz (Python + C/C++)

Method Description:
A hierarchical Graphical Model for an image is build. For each layer
in the hierarchy a Random forest is trained to classify.
Parameters:
Number of trees = 10
Max Depth of Trees = 10
layers in hierarchy = 7

Road/Lane Detection

The following plots show precision/recall curves for the bird's eye view evaluation.


Distance-dependent Behavior Evaluation

The following plots show the F1 score/Precision/Hitrate with respect to the longitudinal distance which has been used for evaluation.


Visualization of Results

The following images illustrate the performance of the method qualitatively on a couple of test images. We first show results in the perspective image, followed by evaluation in bird's eye view. Here, red denotes false negatives, blue areas correspond to false positives and green represents true positives.
