Abstract
In unsupervised VOS, most state-of-the-art methods leverage motion cues obtained from optical flow maps in addition to appearance cues. However, as they are overly dependent on motion cues, which may be unreliable in some cases, they cannot achieve stable prediction. To overcome this limitation, we design a novel motion-as-option network that is not much dependent on motion cues and a collaborative network learning strategy to fully leverage its unique property. Additionally, an adaptive output selection algorithm is proposed to maximize the efficacy of the motion-as-option network at test time.
Preparation
1. Download DUTS, DAVIS, FBMS, YouTube-Objects, and Long-Videos from the official websites.
2. Estimate and save optical flow maps from the videos using RAFT.
3. For convenience, I also provide the pre-processed DUTS, DAVIS, FBMS, YouTube-Objects, and Long-Videos.
4. Replace dataset paths in "run.py" file with your dataset paths.
Training
1. Open the "run.py" file.
2. Specify the model version.
3. Verify the training settings.
4. Start TMO training!
python run.py --train
Testing
1. Open the "run.py" file.
2. Specify the model version and "aos" option.
