For basic dataset information, you can refer to the dataset website.

Before we start, please make sure that you have set environment constants. If not, you can run the following script.

source ../test/env_npu.sh

Step 1. Prepare Annotations

First of all, you can run the following script to prepare annotations.

bash download_annotations.sh

The dataset will be saved in {current_dir}/ucf101

Step 2. Prepare Videos

Then, you can run the following script to prepare videos.

bash download_videos.sh

Step 3. Extract RGB

You can still extract RGB frames using OpenCV by the following script, but it will keep the original size of the images.

bash extract_rgb_frames_opencv.sh

Step 4. Generate File List

You can run the follow script to generate file list in the format of rawframes and videos.

bash generate_videos_filelist.sh
bash generate_rawframes_filelist.sh

Step 5. Move Dataset (Optional)

In this project, we save dataset in directory /opt/npu/ with the follow command

mv ucf101 /opt/npu/

If you save dataset in other path, please modify dataset path in ../config/tsm_k400_pretrained_r50_1x1x8_25e_ucf101_rgb.py.

Step 6. Check Directory Structure

After the whole data process for UCF-101 preparation, you will get the rawframes, videos and annotation files for UCF-101.

In the context of the whole project, the folder structure will look like:
