Setup
Setup environment
conda create -n autolink python=3.8
conda activate autolink
pip install -r requirements.txt
Download datasets
The CelebA-in-the-wild, Taichi, Human3.6m, DeepFashion, CUB, 11k Hands, AFHQ, Horse2Zebra and Flower can be found on their websites. We provide the pre-processing code for CelebA-in-the-wild, CUB and Flower to make them h5
files. Others can be used directly.
Download pre-trained models
The pre-trained models can be downloaded from Google Drive.
Testing
To numerically test the model performance, run
python test.py --log celeba_wild/celeba_wild_k8_m0.8_b16_t0.0025_sklr512 --data_root data/celeba_wild
where,
--log
specifies the checkpoint folder undercheckpoints/
,--data_root
specifies the location of the dataset,
Therefore, the above command will give the performance metric on CelebA-in-the-wild, which is described in the paper.
You can also qualitatively test the model.
python gen_detection.py --log log/celeba_wild_k8_m0.8_b16_t0.0025_sklr512 --folder_name celeba_wild_k8_detection --data_root data/celeba_wild
where,
--folder_name
specifies the folder where you want to save the detection images.
Training
To train our model on CelebA-in-the-wild, run
python train.py --n_parts 8 -missing 0.8 --block 16 --thick 2.5e-3 --sklr 512 --data_root data/celeba_wild -dataset celeba_wild
where,
--n_parts
specifies the number of keypoints,--missing
specifies the ratio of the image masking,--block
specifies number of patches to divide the image in one dimension,--thick
specifies thickness of the edges,--sklr
specifies the learning rate of the edge weights,--data_root
specifies the location of the dataset,--dataset
specifies name of the dataset.
The trained model can be found in checkpoints/celeba_wild_k8_m0.8_b16_t0.0025_sklr512
