SegFlow Results

Segmentation Comparisons with Unsupervised Method

Segmentation Comparisons with Semi-supervised Method

Optical Flow Comparisons

Requirements

• 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.

Demo on DAVIS 2016

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.

Test on your own Videos

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

Training code on DAVIS 2016 (Ours_OL)

Download the segmentation and flow pre-trained weights, and put them in the model folder.
cd training
sh train.sh
