Enhancing Anchor-Based Lane Detection with Auxiliary Semantic Segmentation Supervision

Oyesetan Kolade Oyetola, Sang Jun Lee

Accurate and real-time lane detection is essential for autonomous driving systems. While anchor-based methods such as LaneATT have demonstrated strong performance in both speed and accuracy, they often lack spatial understanding that could be provided by dense semantic segmentation. Conversely, segmentation-based approaches …
