🚀 Dataset Usage

To facilitate researchers, we provide the processed streaming 272-dim Motion Representation of BABEL dataset in this Hugging Face repo.

NOTE: We process the original BABEL dataset to support training of streaming motion generation. e.g. If there is a motion sequence A, annotated as (A1, A2, A3, A4) in BABEL dataset, each subsequence has text description: (A1_t, A2_t, A3_t, A4_t).

Then, our BABEL-stream is constructed as:

seq1: (A1, A2) --- seq1_text: (A1_t*A2_t#A1_length)

seq2: (A2, A3) --- seq2_text: (A2_t*A3_t#A2_length)

seq3: (A3, A4) --- seq3_text: (A3_t*A4_t#A3_length)

Here, * and # is separation symbol, A1_length means the number of frames of subsequence A1.

Motions are resampled into 30 FPS.

The dataset is organized as:

./
  ├── train_stream
      ├── seq1.npy
      ...
  ├── train_stream_text
      ├── seq1.txt
      ...
  ├── val_stream
      ├── seq1.npy
      ...
  ├── val_stream_text
      ├── seq1.txt
      ...

❗️❗️❗️ The processed data is solely for academic purposes. Make sure you read through the BABEL License.
