Abstract: Recent advances like StyleGAN have promoted the growth of controllable facial editing. To address its core challenge of attribute decoupling in a single latent space, attempts have been made to adopt dual-space GAN for better disentanglement of style and content representations. Nonetheless, these methods are still incompetent to obtain plausible editing results with high controllability, especially for complicated attributes. In this study, we highlight the importance of interaction in a dual-space GAN for more controllable editing. We propose TransEditor, a novel Transformer-based framework to enhance such interaction. Besides, we develop a new dual-space editing and inversion strategy to provide additional editing flexibility. Extensive experiments demonstrate the superiority of the proposed framework in image quality and editing capability, suggesting the effectiveness of TransEditor for highly controllable facial editing.

Requirements

A suitable Anaconda environment named transeditor can be created and activated with:

conda env create -f environment.yaml
conda activate transeditor

Dataset Preparation

Datasets CelebA-HQ Flickr-Faces-HQ (FFHQ)
  • You can use download.sh in StyleMapGAN to download the CelebA-HQ dataset raw images and create the LMDB dataset format, similar for the FFHQ dataset.

Download Pretrained Models

  • The pretrained models can be downloaded from TransEditor Pretrained Models.
  • The age classifier and gender classifier for the FFHQ dataset can be found at pytorch-DEX.
  • The out/ folder and psp_out/ folder should be put under the TransEditor/ root folder, the pth/ folder should be put under the TransEditor/our_interfaceGAN/ffhq_utils/dex folder.

Training New Networks

To train the TransEditor network, run

python train_spatial_query.py $DATA_DIR --exp_name $EXP_NAME --batch 16 --n_sample 64 --num_region 1 --num_trans 8

For the multi-gpu distributed training, run

python -m torch.distributed.launch --nproc_per_node=$GPU_NUM --master_port $PORT_NUM train_spatial_query.py $DATA_DIR --exp_name $EXP_NAME --batch 16 --n_sample 64 --num_region 1 --num_trans 8

To train the encoder-based inversion network, run

# FFHQ
python psp_spatial_train.py $FFHQ_DATA_DIR --test_path $FFHQ_TEST_DIR --ckpt .out/transeditor_ffhq/checkpoint/790000.pt --num_region 1 --num_trans 8 --start_from_latent_avg --exp_dir $INVERSION_EXP_NAME --from_plus_space 

# CelebA-HQ
python psp_spatial_train.py $CELEBA_DATA_DIR --test_path $CELEBA_TEST_DIR --ckpt ./out/transeditor_celeba/checkpoint/370000.pt --num_region 1 --num_trans 8 --start_from_latent_avg --exp_dir $INVERSION_EXP_NAME --from_plus_space

Testing (Image Generation/Interpolation)

# sampled image generation
python test_spatial_query.py --ckpt ./out/transeditor_ffhq/checkpoint/790000.pt --num_region 1 --num_trans 8 --sample

# interpolation
python test_spatial_query.py --ckpt ./out/transeditor_ffhq/checkpoint/790000.pt --num_region 1 --num_trans 8 --dat_interp

Inversion

We provide two kinds of inversion methods.

Encoder-based inversion

# FFHQ
python dual_space_encoder_test.py --checkpoint_path ./psp_out/transeditor_inversion_ffhq/checkpoints/best_model.pt --output_dir ./projection --num_region 1 --num_trans 8 --start_from_latent_avg --from_plus_space --dataset_type ffhq_encode --dataset_dir /dataset/ffhq/test/images

# CelebA-HQ
python dual_space_encoder_test.py --checkpoint_path ./psp_out/transeditor_inversion_celeba/checkpoints/best_model.pt --output_dir ./projection --num_region 1 --num_trans 8 --start_from_latent_avg --from_plus_space --dataset_type celebahq_encode --dataset_dir /dataset/celeba_hq/test/images

Optimization-based inversion

# FFHQ
python projector_optimization.py --ckpt ./out/transeditor_ffhq/checkpoint/790000.pt --num_region 1 --num_trans 8 --dataset_dir /dataset/ffhq/test/images --step 10000

# CelebA-HQ
python projector_optimization.py --ckpt ./out/transeditor_celeba/checkpoint/370000.pt --num_region 1 --num_trans 8 --dataset_dir /dataset/celeba_hq/test/images --step 10000

Image Editing

  • The attribute classifiers for CelebA-HQ datasets can be found in celebahq-classifiers.
  • Rename the folder as pth_celeba and put it under the our_interfaceGAN/celeba_utils/ folder.
CelebA_Attributes attribute_index
Male 0
Smiling 1
Wavy hair 3
Bald 8
Bangs 9
Black hair 12
Blond hair 13

For sampled image editing, run

# FFHQ

# CelebA-HQ
python our_interfaceGAN/edit_all_noinversion_celebahq.py --ckpt ./out/transeditor_celeba/checkpoint/370000.pt --attribute_index 0 --num_sample 150000 # Male
python our_interfaceGAN/edit_all_noinversion_celebahq.py --ckpt ./out/transeditor_celeba/checkpoint/370000.pt --attribute_index 3 --num_sample 150000 # wavy hair
python our_interfaceGAN/edit_all_noinversion_celebahq.py --ckpt ./out/transeditor_celeba/checkpoint/370000.pt --attribute_name pose --num_sample 150000 # pose
