## Segmented ImageNet-1K Subset

A subset of ImageNet-1K that has instance segmentation annotations (classes, boxes, and masks), originally intended for use by the [ViT Prisma Library](https://github.com/soniajoseph/ViT-Prisma).

The annotations were autogenerated by [Grounded Segment Anything](https://github.com/IDEA-Research/Grounded-Segment-Anything).



The total size of the dataset is 12,000 images: 10,000 from ImageNet-1K train and 1,000 each from test and val.

### Organization

Images are organized in the same structure as ImageNet-1K:

```
images/
  train_images/
  val_images/
  test_images/
```

The train and val ImageNet classes can be identified from the filenames. See [imagenet-1k classes](https://huggingface.co/datasets/imagenet-1k/blob/main/classes.py).

Annotations are stored in a similar manner:

```
annotations/
  train_annotations/
    masks/
    boxes/
  val_annotations/
    masks/
    boxes/
  test_annotations/
    masks/
    boxes/
```

`masks` contains `.npy` files (shape NUM_BOXES, H, W), and `boxes` contains `.json` files organized as follows:

```json
{
  "classes": ["aquarium", "goldfish", "goldfish"],
  "boxes": [[3, 2, 1160, 564], [1, 131, 447, 547], [3, 2, 1159, 564]],
  "scores": [0.48, 0.4, 0.27]
}
```
The filenames match the corresponding images.
