+# Spatiallysaying/obb-303-65-65
+
+This dataset provides deterministic splits derived from `Spatiallysaying/obb`.
+
+## Source & Method
+- Source splits: `train=346`, `validation=87` (total 433)
+- New splits: `train=303`, `validation=65`, `test=65`
+- Policy: test=15% of total; validation=15% of total carved from the remaining 85%
+- Seed: 1337
+- Procedure: using 🧡 Datasets `train_test_split` twice for deterministic partitioning.
+
+## Notes
+- Task: Semantic segmentation (image + mask).
+- Background label should be 0; ignored regions may use 255.
+- Please cite the original dataset and respect its license.
