| # ASHEN Dataset |
|
|
| ASHEN is a CCTV/surveillance video anomaly dataset organized for weakly supervised video anomaly detection and frame-level evaluation. |
|
|
| ## Dataset Layout |
|
|
| ```text |
| anomaly/ |
| Arson/ |
| Assault/ |
| Burglary/ |
| Explosion/ |
| Fighting/ |
| Robbery/ |
| Shooting/ |
| Vandalism/ |
| normal/ |
| splits_v2_native/ |
| testvidtai/ |
| ``` |
|
|
| ## Current Version |
|
|
| - Anomaly classes: 8 |
| - Published native protocol: 1,600 videos |
| - Anomaly videos: 800 (100 per anomaly class) |
| - Normal videos used by the native protocol: 800 |
| - Native training split: 1,300 videos (650 anomaly + 650 normal) |
| - Native test split: 300 videos (150 anomaly + 150 normal) |
|
|
| Only videos listed under `splits_v2_native/` belong to the official evaluation |
| protocol. The two auxiliary `testvidtai` videos are not part of training or |
| evaluation. |
|
|
| ## Anomaly Classes |
|
|
| - Arson |
| - Assault |
| - Burglary |
| - Explosion |
| - Fighting |
| - Robbery |
| - Shooting |
| - Vandalism |
|
|
| ## Splits and Temporal Annotations |
|
|
| The current protocol is stored in: |
|
|
| ```text |
| splits_v2_native/ |
| ``` |
|
|
| Important files: |
|
|
| - `train_anomaly.txt` |
| - `train_normal.txt` |
| - `test_anomaly.txt` |
| - `test_normal.txt` |
| - `Temporal_Anomaly_Annotation_for_Testing_Videos.txt` |
| - `annotation_todo.csv` |
| - `Temporal_Anomaly_Annotation_for_Testing_Videos.todo.txt` |
| - `protocol.json` |
|
|
| Frame-level temporal annotation is complete for all 150 anomalous test videos. |
| `annotation_todo.csv` and the `.todo.txt` file are retained as annotation audit |
| artifacts; despite their historical names, they do not contain unfinished |
| records. The canonical evaluation file is |
| `Temporal_Anomaly_Annotation_for_Testing_Videos.txt`. |
|
|
| Temporal intervals use frame indices with the convention: |
|
|
| ```text |
| video_name label start1 end1 start2 end2 |
| ``` |
|
|
| `-1 -1` denotes that the second interval is absent. |
|
|
| The temporal annotation file has exactly one row for each anomalous test video. |
| Normal test videos are interpreted as entirely normal and therefore do not |
| need rows in the temporal annotation file. |
|
|
| ## Version Note |
|
|
| This release provides the cleaned, UCF-independent native split and manually |
| reviewed temporal annotations. Results should be reported on the fixed 300-video |
| test split, with model/checkpoint selection performed without using test labels. |
