Face parsing

A Pytorch implementation face parsing model trained by CelebAMask-HQ, based on EHANet.

Dependencies

• Pytorch 1.7.1
• numpy
• Python3
• Pillow
• opencv-python
• tenseorboardX
• pandas
• (Optional) inplace_abn

Preprocessing

• Prepare training data: -- download CelebAMask-HQ dataset
• Move the mask folder, the image folder, and CelebA-HQ-to-CelebA-mapping.txt under ./Data_preprocessing
• Run python g_mask.py to merge separate labels. Support multiprocess, use python g_mask.py --num_process 4 for 4 processes.
• Run python g_partition.py to split train set and test set.

Training

• Run bash run_train.sh #GPU_USE_INDEX, for example, bash run_train.sh 0.
• Add --parallel True in bash script if you want to use multi-GPU for training.

Well-trained model

• The model can be downloaded here (96M).
• The model (#num.pth) should be put under ./models/FaceParseNet50/
• Mask labels are defined as following:

• Overall Per-pixel Acc: 94.26;
• Mean IoU: 76.64;
• Overall F1 Score: 85.33.
• Note: train and evaluate according to CelebA train/test split.

Testing & Color visualization

• Run bash run_test.sh #GPU_num #Model_num, for example, bash run_test.sh 0 32, which uses epoch 32 model file (32_G.pth).
• Pred results will be saved in ./test_pred_results
• Color visualized results will be saved in ./test_color_visualize
• Another way for color visualization without using GPU: Run python ./Data_preprocessing/g_color.py

Visual Results

• OriginalImg vs. GroundTruth vs. PredResult
