LaRS (Lakes, Rivers and Seas Dataset)
LaRS is the largest and most diverse panoptic maritime obstacle detection dataset.
Highlights:
- Diverse scenes from manual capture, public online videos and existing datasets
- USV-centric point of view
- 4000+ manually per-pixel labelled frames:
- 3 stuff categories and 8 thing (dynamic obstacles) categories
- 20 scene-level attributes (e.g. illumination, reflections, conditions)
- Temporal context for each annotated frame (9 preceding frames, total: 40k frames)

Papers archive 2025-07-28
2 shown of 2 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 5. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
