VIL-100: A New Dataset and A Baseline Model for Video Instance Lane Detection
This addresses the need for video-based lane detection in autonomous driving, but it is incremental as it builds on existing lane detection and video object segmentation approaches.
The authors tackled the problem of lane detection in autonomous driving by introducing a new video dataset (VIL-100) with 100 videos and 10,000 annotated frames, and a baseline model (MMA-Net) that outperforms state-of-the-art methods.
Lane detection plays a key role in autonomous driving. While car cameras always take streaming videos on the way, current lane detection works mainly focus on individual images (frames) by ignoring dynamics along the video. In this work, we collect a new video instance lane detection (VIL-100) dataset, which contains 100 videos with in total 10,000 frames, acquired from different real traffic scenarios. All the frames in each video are manually annotated to a high-quality instance-level lane annotation, and a set of frame-level and video-level metrics are included for quantitative performance evaluation. Moreover, we propose a new baseline model, named multi-level memory aggregation network (MMA-Net), for video instance lane detection. In our approach, the representation of current frame is enhanced by attentively aggregating both local and global memory features from other frames. Experiments on the new collected dataset show that the proposed MMA-Net outperforms state-of-the-art lane detection methods and video object segmentation methods.
