| ## HM-World |
|
|
| `HM-World` is a dataset for hybrid memory in dynamic video world models. It provides video sequences, foreground masks, camera pose annotations, character pose annotations, event timestamps, and text captions for each sample. |
|
|
| ## Usage |
|
|
| Merge the split archives and extract the dataset with: |
|
|
| ```bash |
| cat HM-World_* | tar -xzvf - |
| ``` |
|

|
| - `cond.mp4`: condition video. |
| - `tgt.mp4`: target video. |
| - `cond_mask.mp4`: foreground mask video for the condition video. |
| - `tgt_mask.mp4`: foreground mask video for the target video. |
| - `camera.json`: camera pose information. |
| - `character.json`: character pose information. |
| - `check.json`: timestamps that record when the subjects enters or leaves the frame. |
| - `caption.txt`: captions for all samples in the dataset. |
