Installation

• Install Caffe: http://caffe.berkeleyvision.org/.

• Install MATLAB

• Clone this repo

git clone https://github.com/wenz116/TransferSeg.git
cd TransferSeg

• Prepare for MBS

1. Go to the folder utils/MBS/mex.

2. Modify the opencv include and lib paths in compile.m/compile_win.m (for Linux/Windows).

3. Run compile/compile_win in MATLAB (for Linux/Windows).

Dataset

• Download the PASCAL VOC Dataset as the source image dataset, and put it in the data/PASCAL/VOC2011 folder.

• Download the DAVIS Dataset as the target video dataset, and put it in the data/DAVIS folder.

Training

• Download the FCN model pre-trained on PASCAL VOC, and put it in the nets folder.

• Go to the folder scripts.

1. Compute optical flow of the input video. Run compute_optical_flow('<VIDEO_NAME>') in MATLAB. The optical flow images will be saved at data/DAVIS/Motion/480p/<VIDEO_NAME>/.

2. Compute motion prior of the input video via minimum barrier distance. Run get_prior('<VIDEO_NAME>') in MATLAB. The motion prior images will be saved at data/DAVIS/Prior/480p/<VIDEO_NAME>/.

3. Extract features of each category in PASCAL VOC. The extracted features will be saved at cache/features/, named as features_PASCAL_<CLASS_NAME>_fc7.p.

python get_feature_PASCAL.py <GPU_ID>

4. Extract features of the input video. The extracted features will be saved at cache/features/, named as features_DAVIS_<VIDEO_NAME>_fc7.p.

python get_feature_DAVIS.py <GPU_ID> <VIDEO_NAME>

5. Segment mining. The selected segments will be saved at data/DAVIS/Train/480p/<VIDEO_NAME>/.

python get_score.py <GPU_ID> <VIDEO_NAME>

6. Self learning. The trained models will be saved at output/snapshot/.

./train.sh <GPU_ID> <VIDEO_NAME>
