+# Crop parameters
+
+One square crop box per clip that frames the signer, found by running a YOLO person detector on every frame
+(code: [crop-params](https://github.com/croco-corp/crop-params)). The videos are stored uncropped; the crop is
+applied when loading data.
+
+- `crop_params.lmdb/`: LMDB with the clip key (the `__key__` of the segment record) as key and a msgpack map as
+  value: `x_start`, `y_start`, `x_end`, `y_end` and `padding` (`top`, `bottom`, `left`, `right`). It covers all
+  39,813 segments, before the dataset filters.
+- `failed.csv`: the 4 clips that could not be opened (`video_name`, `exception`).
+
+```python
+import lmdb, msgpack
+
+env = lmdb.open("crop_params.lmdb", readonly=True, lock=False)
+with env.begin() as txn:
+    box = msgpack.unpackb(txn.get(b"001_000_M"))
+```
