SelectAnyTree: A Promptable Instance Segmentation Model for 3D Forest LiDAR Point Clouds

Read the original on arXiv Computer Vision →

SelectAnyTree is a promptable instance segmentation model designed for 3D forest LiDAR point clouds, enabling users to delineate individual trees with a few clicks. The architecture comprises a sparse voxel scene encoder, a click‑to‑query prompt encoder, and a state‑space query decoder that produces tree masks in linear time, requiring only 19.4 M parameters. Across seven forest regions and an independent dataset, the model achieves a 79.9 % IoU for a single‑click target tree, outperforming existing promptable baselines and requiring the fewest clicks to reach accuracy targets.

ForestQuery: Boundary-Aware and Spatially Anchored Query Learning for Unified Forest Point Cloud Segmentation

ForestQuery is a new framework for unified forest point cloud segmentation that incorporates boundary-aware and spatially anchored query learning. It explicitly models boundary uncertainty to improve instance query construction and uses learnable 3D anchors to encode forest vertical stratification for semantic queries. Experiments on public benchmarks and a real‑world dataset show consistent gains in both individual‑tree and semantic segmentation.
