PyTorch implementation for self-supervised co-part segmentation.

Paper

Installation

The code is developed based on Pytorch v0.4 with TensorboardX as visualization tools. We recommend to use virtualenv to run our code:

$ virtualenv -p python3 scops_env
$ source scops_env/bin/activate
(scops_env)$ pip install -r requirements.txt

To deactivate the virtual environment, run $ deactivate. To activate the environment again, run $ source scops_env/bin/activate.

SCOPS on Unaligned CelebA

Download data (Saliency, labels, pretrained model)

$ ./download_CelebA.sh

Download CelebA unaligned from here.

Test the pretrained model

$ ./evaluate_celebAWild.sh and accept all default options. The results are stored in a single webpage at results_CelebA/SCOPS_K8/ITER_100000/web_html/index.html.

Train the model

$ CUDA_VISIBLE_DEVICES={GPU} python train.py -f exps/SCOPS_K8_retrain.json where {GPU} is the GPU device number.

SCOPS on Caltech-UCSD Birds

Test the pretrained model

Note: The model is trained with two main differences in the master branch: 1) it is trained with ground truth silhouettes rather than saliency maps. 2) it crops birds w.r.t bounding boxes rather than using the original image.

First set image and annotation path in line 35 and line 37 in dataset/cub.py. Then run:

sh eval_cub.sh

Results as well as visualizations could be found in the results/cub/ITER_60000/train/ folder.
