This repository provides a Tensorflow implementation of our study where we propose a novel end-to-end semi-supervised adversarial framework to generate photorealistic face images of new identities with wide ranges of expressions, poses, and illuminations conditioned by a 3D morphable model.

• TensorFlow 1.2
• Python 3.5

• Generate synthetic images using any 3DMM model i.e. LSFM or Basel Face Model by running gen_syn_latent.m
• Align and crop all datasets using MTCNN to 108x108

Train by the following script

$ python main.py    --log_dir [path2_logdir] --data_dir [path2_datadir] --syn_dataset [synthetic_dataset_name]
                    --dataset [real_dataset_name] --dataset_3dmm [300W-3D & AFLW2000_dirname] --input_scale_size 108

Add --load_path [paused_training_logdir] to continue a training

Generate realistic images after training by the following script

$ python main.py    --log_dir [path2_logdir] --data_dir [path2_datadir] --syn_dataset [synthetic_dataset_name]
                    --dataset [real_dataset_name] --dataset_3dmm [300W-3D & AFLW2000_dirname] --input_scale_size 108
                    --save_syn_dataset [saving_dir] --train_generator False --generate_dataset True --pretrained_gen [path2_logdir + /model.ckpt]
