# Dataset Card for ROPE

<!-- Provide a quick summary of the dataset. -->
The dataset used in this study is designed to evaluate and analyze multi-object hallucination by leveraging existing panoptic segmentation datasets. Specifically, it includes data from MSCOCO-Panoptic and ADE20K, ensuring access to diverse objects and their instance-level semantic annotations. 
For more information, please visit [Multi-Object Hallucination](https://multi-object-hallucination.github.io).

## Dataset Construction

The dataset is divided into several subsets based on the distribution of object classes within each image at test time. This division allows for a more granular analysis of how different distributions affect the hallucination behavior of large vision-language models (LVLMs).

- **Homogeneous**: All tested objects in an image belong to the same class (e.g., AAAAA).
- **Heterogeneous**: All tested objects in an image belong to different classes (e.g., ABCDE).
- **In-the-Wild**: A mixed distribution where the tested objects are randomly chosen and ordered within each image.
- **Adversarial**: A subset designed to challenge the models with difficult object distributions（AAAAB,BAAAA).


## Dataset Statistics
### Training Data Statistics

| Dataset | Total | COCO | ADE |
| :---: | :---: | :---: | :---: |
| Wild | 1539 | 732 | 807 |
| Hom. | 312 | 168 | 144 |
| Het. | 400 | 200 | 200 |
| Adv. | 168 | 54 | 114 |

### Validation Data Statistics

| Dataset | Total | COCO | ADE |
| :---: | :---: | :---: | :---: |
| Wild | 1172 | 547 | 625 |
| Het. | 246 | 76 | 170 |

| Adv. | 334 | 170 | 164 |

## Dataset File Structure
The `ROPE` dataset is structured into training and validation directories, each containing images divided by their object class distributions. Each image directory includes visualizations of bounding boxes (`bbox`) and raw images (`raw`), further categorized into `ADE` and `COCO` sources. The `raw` directory contains the original images, while the `bbox` directory contains the same images with bounding boxes visualized on them.
