| data_files/ |
| omnifall-synthetic_av1.tar OF-Syn video archive (12,000 AV1-encoded MP4s) |
| syn_frame_wise_labels.tar.zst OF-Syn frame-wise HDF5 labels |
| oops_video_mapping.csv Mapping from OOPS original filenames to OF-ItW names |
| prepare_oops_videos.py Script to extract OOPS videos for OF-ItW |
| generate_parquet.py Script to regenerate parquet files from labels + splits |
| ``` |
|
|
| ## Label Format |
|
|
| Each label file in `labels/` contains temporal segment annotations: |
|
|
| ```csv |
| path,label,start,end,subject,cam,dataset |
| path/to/clip,class_id,start_time,end_time,subject_id,camera_id,dataset_name |
| ``` |
|
|
| | Column | Type | Description | |
| |---|---|---| |
| | `path` | string | Relative path to the video (dataset-specific root) | |
| | `label` | int | Class ID (0-15), see [LABELS.md](LABELS.md) | |
| | `start` | float | Segment start time in seconds | |
| | `end` | float | Segment end time in seconds | |
| | `subject` | int | Subject ID (-1 for OF-ItW and OF-Syn) | |
| | `cam` | int | Camera view ID (-1 for OF-ItW and OF-Syn) | |
| | `dataset` | string | Source dataset name | |
|
|
| ### OF-Syn Extended Labels |
|
|
| `labels/of-syn.csv` contains 12 additional demographic and scene metadata columns: |
|
|
| | Column | Values | |
| |---|---| |
| | `age_group` | toddlers_1_4, children_5_12, teenagers_13_17, young_adults_18_34, middle_aged_35_64, elderly_65_plus | |
| | `gender_presentation` | male, female | |
| | `monk_skin_tone` | mst1 through mst10 | |
| | `race_ethnicity_omb` | white, black, asian, hispanic_latino, aian, nhpi, mena | |
| | `bmi_band` | underweight, normal, overweight, obese | |
| | `height_band` | short, avg, tall | |
| | `environment_category` | indoor, outdoor | |
| | `camera_shot` | static_wide, static_medium_wide | |
| | `speed` | 24fps_rt, 25fps_rt, 30fps_rt, std_rt | |
| | `camera_elevation` | eye, low, high, top | |
| | `camera_azimuth` | front, rear, left, right | |
| | `camera_distance` | medium, far | |
|
|
| These fields are available in OF-Syn configs (`of-syn`, `of-syn-cross-*`, `labels-syn`, `metadata-syn`, `framewise-syn`). Cross-domain configs that mix sources use only the 7 core columns. |
|
|
| ## Split Format |
|
|
| Split files in `splits/` list video paths included in each partition: |
|
|
| ```csv |
| path |
| path/to/clip |
| ``` |
|
|
| Each video path maps to one or more temporal segments in the corresponding label file. The parquet configs contain the pre-merged result of joining split paths with labels. |
