PAPER INFO

"ECO: Efficient Convolutional Network for Online Video Understanding"
By Mohammadreza Zolfaghari, Kamaljeet Singh, Thomas Brox
paper link

Environment:

  • Python 3.6.4
  • PyTorch 0.3.1

Clone this repo

git clone https://github.com/zhang-can/ECO-pytorch

Generate dataset lists

python gen_dataset_lists.py <ucf101/something> <dataset_frames_root_path>

e.g. python gen_dataset_lists.py something ~/dataset/20bn-something-something-v1/

The dataset should be organized as:
<dataset_frames_root_path>/<video_name>/<frame_images>

Training

[UCF101 - ECO - RGB] command:

python main.py ucf101 RGB <ucf101_rgb_train_list> <ucf101_rgb_val_list> \
        --arch ECO --num_segments 4 --gd 5 --lr 0.001 --lr_steps 30 60 --epochs 80 \
        -b 32 -i 1 -j 1 --dropout 0.8 --snapshot_pref ucf101_ECO --rgb_prefix img_ \
        --consensus_type identity --eval-freq 1
