1. Download Pascal VOC dataset
Please go to PANet and download VOC dataset and put them under FewShotSeg-dataset/Pascal folder.
# symlink the pascal dataset
mkdir -p FewShotSeg-dataset/Pascal
ln -s /path_to_pascal_dataset/ FewShotSeg-dataset/Pascal/
2. Download pretrained model
Download the ResNet50 and Resnet101 weights and put them under FewShotSeg-dataset/cache/ folder.
3. Download the unlabel superpixel data
Download the unlabel superpixel from here and put it under FewShotSeg-dataset/Pascal/superpixel folder. If you want to generate your own superpixel data, please follow the fast_slic.
