## PartImageNet++ Dataset
PartImageNet++ is an extensive dataset designed for robust object recognition and segmentation tasks. This dataset expands upon the original ImageNet dataset by providing detailed part annotations for each object category.
### Dataset Statistics
| Obj. Cat. | Part Cat. | Img | Part Mask |
| --------- | --------- | ------ | --------- |
| 1000 | 3308 | 100000 | 406364 |
The dataset includes:
- **1000 object categories** derived from the original ImageNet.
- **3308 part categories** representing different parts of objects.
- **100,000 annotated images**, with each object category containing 100 images.
- **406,364 part mask annotations** ensuring comprehensive coverage and detailed segmentation.
### Structure and Contents
Each JSON file in the `json` directory represents one object category and its corresponding part annotations.
The `including` folder provides detailed inclusion relations of parts, illustrating hierarchical relationships between different part categories.
The `discarded_data.json` file lists low-quality images that were excluded from the dataset to maintain high annotation standards.
### Visualizations
We provide a visualization demo tool to explore and inspect the annotations. This tool helps users to better understand the structure and details of the dataset.
