Instance segmentation propagation on DAVIS2017

Method	J_mean	J_recall	J_decay	F_mean	F_recall	F_decay
Ours	0.563	0.650	0.289	0.592	0.641	0.354
Ours - track	0.577	0.683	0.263	0.613	0.698	0.324

Prerequisites

The code is tested in the following environment:

Ubuntu 16.04
Pytorch 1.1.0, tqdm, scipy 1.2.1

Testing on DAVIS2017

Testing without tracking

To test on DAVIS2017 for instance segmentation mask propagation, please run:

python test.py -d /workspace/DAVIS/ -s 480

Important parameters:

-c: checkpoint path.
-o: results path.
-d: DAVIS 2017 dataset path.
-s: test resolution, all results in the paper are tested on 480p images, i.e. -s 480.

Please check the test.py file for other parameters.

Testing with tracking

To test on DAVIS2017 by tracking & propagation, please run:

python test_with_track.py -d /workspace/DAVIS/ -s 480

Similar parameters as test.py, please see the test_with_track.py for details.

Testing on the VIP dataset

To test on VIP, please run the following command with your own VIP path:

python test_mask_vip.py -o results/VIP/category/ --scale_size 560 560 --pre_num 1 -d /DATA/VIP/VIP_Fine/Images/ --val_txt /DATA/VIP/VIP_Fine/lists/val_videos.txt -c weights/checkpoint_latest.pth.tar

and then:

python eval_vip.py -g DATA/VIP/VIP_Fine/Annotations/Category_ids/ -p results/VIP/category/

Testing on the JHMDB dataset

Please check out this branch. The code is borrowed from TimeCycle.

Training on Kinetics

Dataset

We use the kinetics dataset for training.

Training command

python track_match_v1.py --wepoch 10 --nepoch 30 -c match_track_switch --batchsize 40 --coord_switch 0 --lc 0.3
