| # GFM4DBench data package |
|
|
| [Paper](https://arxiv.org/abs/2611.16840) · [Project](https://kosmoresearch.github.io/Kosmo-GFM/) · [Code](https://github.com/KosmoResearch/Kosmo-GFM) · [Model](https://huggingface.co/KosmoResearch/Kosmo-GFM) |
|
|
| TapVid3D / WorldTrack mini and SynthVerse benchmark data used by GFM4DBench. |
|
|
| ## Layout |
|
|
| ```text |
| 4dbenchmark_data/ |
| ├── Tapvid3d_mini/ |
| │ └── Tapvid3d_mini_extracted/ |
| │ ├── adt_mini.json |
| │ ├── pstudio_mini.json |
| │ ├── po_mini.json |
| │ ├── ds_mini.json |
| │ ├── adt_mini/ |
| │ ├── pstudio_mini/ |
| │ ├── po_mini/ |
| │ └── ds_mini/ |
| └── SynthVerse/ |
| ├── synthverse_mini.json |
| └── converted/ |
| ├── converted_subset50_64f_dynamic/ # trajectory arrays |
| │ └── <sequence>/{trajs_3d,visibs} |
| └── <sequence>/rgbs/ |
| ``` |
|
|
| Each TapVid3D subset has 50 sequences. Every sequence contains the RGB frames |
| and the per-frame 3D trajectories and visibility flags. |
|
|
| SynthVerse has 49 sequences of 64 frames and uses the PointOdyssey coordinate |
| convention. It is reported separately from the TapVid3D average. |
|
|
| ## Usage |
|
|
| Point `GFM4D_DATA_ROOT` at this directory (the one containing |
| `Tapvid3d_mini/` and `SynthVerse/`) and run the GFM4DBench evaluator: |
|
|
| ```bash |
| export GFM4D_DATA_ROOT=/path/to/4dbenchmark_data |
| bash bench/GFM4DBench/script/eval.sh dynamic-points --subset pstudio --limit-seqs 1 |
| bash bench/GFM4DBench/script/eval.sh dynamic-points --subset synthverse |
| ``` |
|
|
| The registry shipped with GFM4DBench (`bench/GFM4DBench/configs/subsets.yaml`) |
| already uses the nested paths above. |
|
|
| ## Expected query counts |
|
|
| With the default clip length of 64 frames: |
|
|
| | Subset | Sequences | Frames per sequence | Scored queries | |
| |---|---|---|---| |
| | `adt` | 50 | 300 | 22187 | |
| | `pstudio` | 50 | 150 | 8720 | |
| | `po` | 50 | 128 | 53465 | |
| | `ds` | 50 | 128 | 45149 | |
| | `synthverse` | 49 | 64 | 15762 | |
|
|
| `total_queries` in `summary.json` must match these values. |
|
|
| ## Contents and exclusions |
|
|
| Included: `rgb`, `trajs_3d` and `visibs`; intrinsics and extrinsics are stored |
| directly in the JSON. |
|
|
| Excluded: `depth/`, `trajs_2d/`, `valids/`, `query_track_indices/`, `*.bak` |
| duplicates and the `adt_mini_trajs2d_fixed/` copy. The evaluator never reads |
| them. The JSON files have been cleaned so that no path points to a missing |
| file, and the SynthVerse RGB files are stored as regular files rather than |
| symlinks. |
|
|
| ## Integrity |
|
|
| ```bash |
| sha256sum -c SHA256SUMS |
| ``` |
|
|
| `MANIFEST.json` records the subset statistics and the layout version. |
