STGAN (CVPR 2019)

Tensorflow implementation of STGAN: A Unified Selective Transfer Network for Arbitrary Image Attribute Editing

Overall architecture of our STGAN. Taking the image above as an example, in the difference attribute vector , is set to 1, is set to -1, and others are set to zeros. The outputs of and are the scalar and the vector , respectively

Exemplar Results

• See results.md for more results

• Facial attribute editing results

  
  

  Facial attribute editing results on the CelebA dataset. The rows from top to down are results of IcGAN, FaderNet, AttGAN, StarGAN and STGAN.

  
  

  High resolution () results of STGAN for facial attribute editing.

• Image translation results

  
  

  Results of season translation, the top two rows are , and the bottom two rows are .

Preparation

• Prerequisites

  • Tensorflow (r1.4 - r1.12 should work fine)
  • Python 3.x with matplotlib, numpy and scipy

• Dataset

  • CelebA dataset (Find more details from the project page)
    • Images should be placed in DATAROOT/img_align_celeba/*.jpg
    • Attribute labels should be placed in DATAROOT/list_attr_celeba.txt
    • If google drive is unreachable, you can get the data from Baidu Cloud
  • We follow the settings of AttGAN, kindly refer to AttGAN for more dataset preparation details

• pre-trained model

  • download the model from Google Drive or Baidu Cloud (4qeu), and unzip the files to ./output/,

Quick Start

Exemplar commands are listed here for a quick start.

Training

• for 128x128 images

  python train.py --experiment_name 128

• for 384x384 images (please prepare data according to HD-CelebA)

  python train.py --experiment_name 384 --img_size 384 --enc_dim 48 --dec_dim 48 --dis_dim 48 --dis_fc_dim 512 --n_sample 24 --use_cropped_img

Testing

• Example of testing single attribute

  python test.py --experiment_name 128 [--test_int 1.0]

• Example of testing multiple attributes

  python test.py --experiment_name 128 --test_atts Pale_Skin Male [--test_ints 1.0 1.0]

• Example of attribute intensity control

  python test.py --experiment_name 128 --test_slide --test_att Male [--test_int_min -1.0 --test_int_max 1.0 --n_slide 10]

The arguments in [] are optional with a default value.

View Images

You can use show_image.py to show the generated images, the code has been tested on Windows 10 and Ubuntu 16.04 (python 3.6). If you want to change the width of the buttons in the bottom, you can change width parameter in the 160th line. the '+++' and '---' on the button indicate that the above image is modified to 'add' or 'remove' the attribute. Note that you should specify the path of the attribute file (list_attr_celeba.txt) of CelebA in the 82nd line.

NOTE:

• You should give the path of the data by adding --dataroot DATAROOT;
• You can specify which GPU to use by adding --gpu GPU, e.g., --gpu 0;
• You can specify which image(s) to test by adding --img num (e.g., --img 182638, --img 200000 200001 200002), where the number should be no larger than 202599 and is suggested to be no smaller than 182638 as our test set starts at 182638.png.
• You can modify the model by using following arguments
  • --label: 'diff'(default) for difference attribute vector, 'target' for target attribute vector
  • --stu_norm: 'none'(default), 'bn' or 'in' for adding no/batch/instance normalization in STUs
  • --mode: 'wgan'(default), 'lsgan' or 'dcgan' for differenct GAN losses
  • More arguments please refer to train.py

AttGAN

• Train with AttGAN model by

  python train.py --experiment_name attgan_128 --use_stu false --shortcut_layers 1 --inject_layers 1
