WoodBR-Cross: A public wood-image dataset and individual-tree-disjoint benchmark for species identification

Wood-image benchmarks can yield optimistic estimates when images from the same tree occur in both training and test sets.

Key points

  • WoodBR-Cross contains 4,875 transverse-surface images in 38 operational taxonomic classes, linked to 303 distinct trees identified by numeric catalogue witness codes (codigos-testemunho) in the Brazilian Forest Service collection.
  • A species-level subset comprises 3,406 images, 20 classes and 214 trees.
  • Three tasks compare duplicate-aware image partitions for all classes (A), image partitions for the species subset (B1), and individual-tree-disjoint partitions for that subset (B2).
  • Validation-selected ConvNeXt-Tiny achieved B2 tree-level macro-F1 of 0.8621 +/- 0.0317; frozen DINOv2 features yielded 0.9000 +/- 0.0722.
