Motion-Attentive Transition for Zero-Shot Video Object Segmentation

PWC

PWC

UPDATES:

  • [2021/04/17] Our MATNet achieves state-of-the-art results (64.2 in terms of Mean J) on the MoCA dataset in "Self-supervised Video Object Segmentation by Motion Grouping" by Charig Yang, Hala Lamdouar, Erika Lu, Andrew Zisserman, Weidi Xie. Thanks Charig Yang for providing the segmentation results Google Drive.
  • [2020/06/15] Update results for DAVIS-17 test-dev set!
  • [2020/03/04] Update results for DAVIS-17 validation set!
  • [2019/11/17] Codes released!

This is a PyTorch implementation of our MATNet for unsupervised video object segmentation.

Motion-Attentive Transition for Zero-Shot Video Object Segmentation. [Arxiv] [TIP]

Prerequisites

The training and testing experiments are conducted using PyTorch 1.0.1 with a single GeForce RTX 2080Ti GPU with 11GB Memory.

Other minor Python modules can be installed by running

pip install -r requirements.txt

Train

Clone

git clone --recursive https://github.com/tfzhou/MATNet.git

Download Datasets

In the paper, we use the following two public available dataset for training. Here are some steps to prepare the data:

  • DAVIS-17: we use all the data in the train subset of DAVIS-16. However, please download DAVIS-17 to fit the code. It will automatically choose the subset of DAVIS-16 for training.

  • YoutubeVOS-2018: we sample the training data every 10 frames in YoutubeVOS-2018. We use the dataset version with 6fps rather than 30fps.

  • Create soft links:

    cd data; ln -s your/davis17/path DAVIS2017; ln -s your/youtubevos/path YouTubeVOS_2018;

Prepare Edge Annotations

I have provided some matlab scripts to generate edge annotations from mask. Please run data/run_davis2017.m and data/run_youtube.m.

Prepare HED Results

I have provided the pytorch codes to generate HED results for the two datasets (see 3rdparty/pytorch-hed). Please run run_davis.py and run_youtube.py.

The codes are borrowed from https://github.com/sniklaus/pytorch-hed.

Prepare Optical Flow

I have provided the pytorch codes to generate optical flow results for the two datasets (see 3rdparty/pytorch-pwc). Please run run_davis_flow.py and run_youtubevos_flow.py.

The codes are borrowed from https://github.com/sniklaus/pytorch-pwc. Please follow the setup section to install cupy.

warning: Total size of optical flow results of Youtube-VOS is more than 30GB.

Train

Once all data is prepared, please run python train_MATNet.py for training.

Test

  1. Run python test_MATNet.py to obtain the saliency results on DAVIS-16 val set.
  2. Run python apply_densecrf_davis.py for binary segmentation results.

Segmentation Results

  1. The segmentation results on DAVIS-16 and Youtube-objects can be downloaded from Google Drive.
  2. The segmentation results on DAVIS-17 val can be downloaded from Google Drive. We achieved 58.6 in terms of Mean J&F.
  3. The segmentation results on DAVIS-17 test-dev can be downloaded from Google Drive. We achieved 59.8 in terms of Mean J&F. The method also achieved the second place in DAVIS-20 unsupervised object segmentation challenge. Please refer to paper for more details of our challenge solution.

Pretrained Models

The pre-trained model can be downloaded from Google Drive.
