We manage the project using three different repositories (which are actually in the paper title). This is the main repo, see also Mask-Propagation and Scribble-to-Mask.

Framework

Requirements

We used these packages/versions in the development of this project. It is likely that higher versions of the same package will also work. This is not an exhaustive list -- other common python packages (e.g. pillow) are expected and not listed.

PyTorch 1.7.1
torchvision 0.8.2
OpenCV 4.2.0
Cython
progressbar
davis-interactive (https://github.com/albertomontesg/davis-interactive)
PyQt5 for GUI
networkx 2.4 for DAVIS
gitpython for training
gdown for downloading pretrained models

Refer to the official PyTorch guide for installing PyTorch/torchvision. The rest can be installed by:

pip install PyQt5 davisinteractive progressbar2 opencv-python networkx gitpython gdown Cython

Quick start

GUI

python download_model.py to get all the required models.
python interactive_gui.py --video <path to video> or python interactive_gui.py --images <path to a folder of images>. A video has been prepared for you at example/example.mp4.
If you need to label more than one object, additionally specify --num_objects <number_of_objects>. See all the argument options with python interactive_gui.py --help.
There are instructions in the GUI. You can also watch the demo videos for some ideas.

DAVIS Interactive VOS

See eval_interactive_davis.py. If you have downloaded the datasets and pretrained models using our script, you only need to specify the output path, i.e., python eval_interactive_davis.py --output [somewhere].

DAVIS/YouTube Semi-supervised VOS

Go to this repo: Mask-Propagation.

Main Results

DAVIS/YouTube semi-supervised results

DAVIS Interactive Track

All results are generated using the unmodified official DAVIS interactive bot without saving masks (--save_mask not specified) and with an RTX 2080Ti. We follow the official protocol.

Baseline	86.0	86.6
(+) Top-k	87.2	87.8

Full model, without BL30K for propagation/fusion	87.4	88.0
Full model, STCN backbone	88.4	88.8

Pretrained models

python download_model.py should get you all the models that you need. (pip install gdown required.)

Training

Data preparation

Datasets should be arranged as the following layout. You can use download_datasets.py (same as the one Mask-Propagation) to get the DAVIS dataset and manually download and extract fusion_data ([OneDrive]) and BL30K.

BL30K

BL30K is a synthetic dataset rendered using Blender with ShapeNet's data. We break the dataset into six segments, each with approximately 5K videos. The videos are organized in a similar format as DAVIS and YouTubeVOS, so dataloaders for those datasets can be used directly. Each video is 160 frames long, and each frame has a resolution of 768*512. There are 3-5 objects per video, and each object has a random smooth trajectory -- we tried to optimize the trajectories greedily to minimize object intersection (not guaranteed), with occlusions still possible (happen a lot in reality). See generation/blender/generate_yaml.py for details.

We noted that using probably half of the data is sufficient to reach full performance (although we still used all), but using less than one-sixth (5K) is insufficient.

Download

You can either use the automatic script download_bl30k.py or download it manually below. Note that each segment is about 115GB in size -- 700GB in total. You are going to need ~1TB of free disk space to run the script (including extraction buffer).

Google Drive is much faster in my experience. Your mileage might vary.

Manual download: [Google Drive] [OneDrive]

Note: Google might block the Google Drive link. You can 1) make a shortcut of the folder to your own Google Drive, and 2) use rclone to copy from your own Google Drive (would not count towards your storage limit).

[UST Mirror] (Reliability not guaranteed, speed throttled, do not use if others are available): ckcpu1.cse.ust.hk:8080/MiVOS/BL30K_{a-f}.tar (Replace {a-f} with the part that you need).

Generation

Download ShapeNet.
Install Blender. (We used 2.82)
Download a bunch of background and texture images. We used this repo (we specified "non-commercial reuse" in the script) and the list of keywords are provided in generation/blender/*.json.
Generate a list of configuration files (generation/blender/generate_yaml.py).
Run rendering on the configurations. See here (Not documented in detail, ask if you have a question)

Fusion data

We use the propagation module to run through some data and obtain real outputs to train the fusion module. See the script generate_fusion.py.

Or you can download pre-generated fusion data: [Google Drive] [OneDrive]

Training commands

These commands are to train the fusion module only.

CUDA_VISIBLE_DEVICES=[a,b] OMP_NUM_THREADS=4 python -m torch.distributed.launch --master_port [cccc] --nproc_per_node=2 train.py --id [defg] --stage [h]

We implemented training with Distributed Data Parallel (DDP) with two 11GB GPUs. Replace a, b with the GPU ids, cccc with an unused port number, defg with a unique experiment identifier, and h with the training stage (0/1).

The model is trained progressively with different stages (0: BL30K; 1: DAVIS). After each stage finishes, we start the next stage by loading the trained weight. A pretrained propagation model is required to train the fusion module.

One concrete example is:

Pre-training on the BL30K dataset: CUDA_VISIBLE_DEVICES=0,1 OMP_NUM_THREADS=4 python -m torch.distributed.launch --master_port 7550 --nproc_per_node=2 train.py --load_prop saves/propagation_model.pth --stage 0 --id retrain_s0

Main training: CUDA_VISIBLE_DEVICES=0,1 OMP_NUM_THREADS=4 python -m torch.distributed.launch --master_port 7550 --nproc_per_node=2 train.py --load_prop saves/propagation_model.pth --stage 1 --id retrain_s012 --load_network [path_to_trained_s0.pth]
