# AmbiBench Metadata

This dataset provides the **metadata** used in the AmbiBench benchmark.  
Each row corresponds to an ambiguous image or video sample paired with a question–answer pair, derived from the benchmark design.

---

## Columns

### `question`
- The natural-language question posed to the model.  

### `answer`
- The reference answer to the `question`.  
- May include:
  - A single object name (`"snake"`),  
  - A semicolon-separated pair for bistable/multi-scene (`"duck; rabbit"`),  
  - Or multiple objects/scenes (`"bear, deer, wolf, bird"`).

### `file_name`
- Cleaned filename of the associated image or video.  
- Any inline bounding box tags in the original filename (e.g.  
  `2120_netimg_hidden_face_illusion_[1152,807,1392,1263].jpg`)  
  are removed, and the coordinates are stored separately in `bbox`.  
- ⚠️ **Special case: `motion_video` samples** — the stored file names end with `.png` as placeholders.  
  For actual usage, replace `.png` with `.mp4` to access the corresponding video file.

### `bbox`
- A list of bounding box coordinates `[x1, y1, x2, y2]` if required by the question.  
- Empty list (`[]`) if no bounding box is provided.  

### `type`
- Combined label = **Ambiguity category** (*from the AmbiBench taxonomy*) + **Task type**.  
- Categories include:  
  *Camouflaged, Bistable, Hybrid, Color, Multi-view, Geometric, Motion, Multi-scene, Mixed*.  
- Task types include: *open-ended, localization(bbox), region*.  
- Example values:  
  - `"camouflaged_open"`  
  - `"mix_bbox"`  
  - `"mix_highlighted"`

---

## Notes
- All entries include consistent fields: `question`, `answer`, `file_name`, `bbox`, `type`.  
- `motion_video` entries must be linked to the corresponding `.mp4` files (replace `.png` extension).  
- This metadata is suitable for training and evaluating vision–language models on ambiguous image understanding.
