Segmentation Comparisons with Unsupervised Method

Segmentation Comparisons with Semi-supervised Method

Optical Flow Comparisons

• Install caffe and pycaffe (opencv is required).
  cd caffe
make all -j8 (paths are needed to change in the configuration file)
  make pycaffe
  

• Download the DAVIS 2016 dataset and put it in the data folder.

• Download our pre-trained caffe model here and put it in the model folder.

cd demo
python infer_DAVIS.py VIDEO_NAME
For example, run python infer_DAVIS.py dog

This code provides a demo for the parent net (Ours_OL) in SegFlow. The output contains both the segmentation and optical flow results.

cd demo
python infer_video.py VIDEO_FILE
For example, run python infer_video.py ../data/video_example.mp4

• SegFlow without online training step (Ours_OL) here
• SegFlow without optical flow branch (Ours_FLO) here
• Final SegFlow results here

The model and code are available for non-commercial research purposes only.
