Research questionHow can maritime LiDAR detect both small sparse vessels and large-vessel structure amid sea clutter?Small vessels may produce only a few informative LiDAR points, while large vessels require modeling geometric relationships beyond local neighborhoods. Sea clutter further complicates distinguishing vessel structure from the surrounding environment without relying on computationally expensive dense representations.
