Editing Tasks

Pre-trained Models

Please download the pre-trained models from the following links and save them to models/pretrain/

Description Generator Encoder
Model trained on FFHQ dataset. face_256x256_generator face_256x256_encoder
Model trained on LSUN Tower dataset. tower_256x256_generator tower_256x256_encoder
Model trained on LSUN Bedroom dataset. bedroom_256x256_generator bedroom_256x256_encoder
Perceptual Model

Inversion

MODEL_NAME='styleganinv_ffhq256'
IMAGE_LIST='examples/test.list'
python invert.py $MODEL_NAME $IMAGE_LIST

NOTE: We find that 100 iterations are good enough for inverting an image, which takes about 8s (on P40). But users can always use more iterations (much slower) for a more precise reconstruction.

Semantic Diffusion

MODEL_NAME='styleganinv_ffhq256'
TARGET_LIST='examples/target.list'
CONTEXT_LIST='examples/context.list'
python diffuse.py $MODEL_NAME $TARGET_LIST $CONTEXT_LIST

NOTE: The diffusion process is highly similar to image inversion. The main difference is that only the target patch is used to compute loss for masked optimization.

Interpolation

SRC_DIR='results/inversion/test'
DST_DIR='results/inversion/test'
python interpolate.py $MODEL_NAME $SRC_DIR $DST_DIR

Manipulation

IMAGE_DIR='results/inversion/test'
BOUNDARY='boundaries/expression.npy'
python manipulate.py $MODEL_NAME $IMAGE_DIR $BOUNDARY

NOTE: Boundaries are obtained using InterFaceGAN.

Style Mixing

STYLE_DIR='results/inversion/test'
CONTENT_DIR='results/inversion/test'
python mix_style.py $MODEL_NAME $STYLE_DIR $CONTENT_DIR
