Installation

Clone this repository

git clone https://github.com/maoyunyao/JOINT.git

Install dependencies

Please check the detailed installation instructions.

Training

The whole network is trained with 8 NVIDIA GTX 1080Ti GPUs

conda activate pytracking
cd ltr
python run_training.py joint joint_stage1  # stage 1
python run_training.py joint joint_stage2  # stage 2

Note: We initialize the backbone ResNet with pre-trained Mask-RCNN weights as in LWL. These weights can be obtained from here. Before training, you need to download and save these weights in env_settings().pretrained_networks directory.

Evaluation

conda activate pytracking
cd pytracking
python run_tracker.py joint joint_davis --dataset_name dv2017_val        # DAVIS 2017 Val
python run_tracker.py joint joint_ytvos --dataset_name yt2018_valid_all  # YouTube-VOS 2018 Val
python run_tracker.py joint joint_ytvos --dataset_name yt2019_valid_all  # YouTube-VOS 2019 Val

Note: Before evaluation, the pretrained networks (see model zoo) should be downloaded and saved into the directory set by "network_path" in "pytracking/evaluation/local.py". By default, it is set to pytracking/networks.

Acknowledgments

• Our JOINT segmentation tracker is implemented based on pytracking. We sincerely thank the authors Martin Danelljan and Goutam Bhat for providing such a great framework.
• We adopt the few-shot learner proposed in LWL as the Induction branch.
