Fast pixelwise road inference based on Uniformly Reweighted Belief Propagation

The future of autonomous vehicles and driver assistance systems is underpinned by the need of fast and efficient approaches for road scene understanding. Despite the large explored paths for road detection, there is still a research gap for incorporating image understanding capabilities in intelligent vehicles. This paper presents a pixelwise segmentation of roads from monocular images. The proposal is based on a probabilistic graphical model and a set of algorithms and configurations chosen to speed up the inference of the road pixels. In brief, the proposed method employs Conditional Random Fields and Uniformly Reweighted Belief Propagation. Besides, the approach is ranked on the KITTI ROAD dataset yielding state-of-the-art results with the lowest runtime per image using a standard PC.
