This repo contains the manually annotated dataset, **iGround**, introduced in the paper *"Large-scale Pre-training for Grounded Video Caption Generation"*.

## 📦 Loading the Dataset

 You can load each configuration and split directly with the 🤗 Datasets library:

 ```python
from datasets import load_dataset

 repo = "ekazakos/iGround"

 # Available configs:
# - data_processed
# - data_raw
# - keys
#
# Each config includes the standard splits: train, val, and test.

 # data_processed: annotations after processing used to train GROVE.
#   Processing merges multiple instances of the same object type in a clip
#   into a single annotation by taking the union of all boxes for that instance.
ds_proc_train = load_dataset(repo, "data_processed", split="train")
ds_proc_val = load_dataset(repo, "data_processed", split="val")
ds_proc_test = load_dataset(repo, "data_processed", split="test")

 # data_raw: raw annotations without any processing.
#   The same object type can appear multiple times in a video,
#   with distinct bounding boxes per instance and per frame.
ds_raw_train = load_dataset(repo, "data_raw", split="train")
ds_raw_val = load_dataset(repo, "data_raw", split="val")
ds_raw_test = load_dataset(repo, "data_raw", split="test")

 # keys: contains the corresponding video_ids for the above splits.
ds_keys_train = load_dataset(repo, "keys", split="train")
ds_keys_val = load_dataset(repo, "keys", split="val")
```
