Installation

Docker build

$ sh build_img.sh
$ sh build_container.sh [container-name]

Install package

$ docker start [container-name]
$ docker attach [container-name]
$ pip install -v -e .

Pretrained weights

• dlib landmarks detector
• FFHQ e4e encoder
• FFHQ stylegan2-ada
• IR-SE50

Download and save this pretrained weights in pretrained/ directory

Extract W, S, S_mean, S_std

FFHQ1024

$ python extract.py

FFHQ256

$ python extract.py --ckpt=pretrained/ffhq256.pkl --dataset_name=ffhq256

Extract global image direction

FFHQ1024

$ python manipulator.py extract

FFHQ256

$ python manipulator.py extract --ckpt=pretrained/ffhq256.pkl --face_preprocess=True --dataset_name=ffhq256

RUN demo.ipynb on jupyter notebook

• Scripts for CLI env will be added.

Manipulation option

• Source image
  • Input image projection
  • Generate z from random seed
• Text description(neutral, target)
• Manipulation strength (alpha)
• Disentangle threshold (beta)

TODO

• Save generator checkpoint by generated by pivot tuning inversion(FFHQ)
• Global direction module refactoring(especially in gpu usage)
