+ # The test split of Drag-a-Move dataset
2
+
3
+ This test set is used to evaluate [DragAPart](https://dragapart.github.io/) and [Puppet-Master](https://vgg-puppetmaster.github.io/).
4
+
5
+ ### How to use it?
6
+
7
+ 1. **Frame folders & Ground‑truth videos**
8
+ Under the dataset root, each sample has its own sub‑folder.
9
+ Inside each sub‑folder you will find **14 PNG frames** extracted from the ground‑truth video:
10
+
11
+ {sample_id}/
12
+ cXXX_tYYY.png
13
+ cXXX_tYYY.png
14
+
15
+
16
+ where `cXXX` is the zero‑padded camera index and `tYYY` is the zero‑padded frame index.
17
+
18
+ 2. **Metadata**
19
+ A `metadata.json` file in the dataset root maps each sample ID to two fields:
20
+
21
+ * `reverse` — `true` if the original motion runs backward (larger frame index first), otherwise `false`.
22
+ * `per_frame_drags` — the sparse motion trajectories as drags. It's an array of shape (14, 5, 4), where it specifies the starting coordinates and ending coordinates of the 5 drags on the 14 frames. The coordinates are normalized to [0, 1] range.
