Dataset Card for UCF101

UCF101 is an action recognition data set of realistic action videos collected from YouTube, having 101 action categories. This version of the dataset does not contain images but images saved frame by frame. Train and test splits are generated based on the authors' first version train/test list.

Dataset Details

The UCF101 includes 13320 videos from 101 action categories. For more details, visit the website and the publication specified below.

Uses

In order to prepare the dataset for the FL settings, we recommend using Flower Dataset (flwr-datasets) for the dataset download and partitioning and Flower (flwr) for conducting FL experiments.

To partition the dataset, do the following.

1. Install the package.

pip install flwr-datasets[vision]

2. Use the HF Dataset under the hood in Flower Datasets.

from flwr_datasets import FederatedDataset
from flwr_datasets.partitioner import NaturalIdPartitioner

fds = FederatedDataset(
    dataset="flwrlabs/ucf101",
    partitioners={"train": NaturalIdPartitioner(partition_by="video_id")}
)
partition = fds.load_partition(partition_id=0)

Data Instances

The first instance of the train split is presented below:

{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=320x240>,
 'video_id': 'v_ApplyEyeMakeup_g08',
 'clip_id': 'v_ApplyEyeMakeup_g08_c01',
 'frame': 1,
 'label': 0}
