It is the training program for libfacedetection. The source code is based on FaceBoxes.PyTorch and ssd.pytorch.

• Installation
• Training
• Detection
• Export CPP source code
• Design your own model

1. Install PyTorch >= v1.0.0 following official instruction.

2. Clone this repository. We will call the cloned directory as $TRAIN_ROOT.

git clone https://github.com/ShiqiYu/libfacedetection.train

Note: Codes are based on Python 3+.

1. Download WIDER FACE dataset, place the images under this directory:

$TRAIN_ROOT/data/WIDER_FACE_rect/images

and create a symbol link to this directory from

$TRAIN_ROOT/data/WIDER_FACE_landmark/images

2. Train the model using WIDER FACE:

cd $TRAIN_ROOT/tasks/task1/
python3 train.py

cd $TRAIN_ROOT/tasks/task1/
./detect.py -m weights/yunet_final.pth --image_file=filename.jpg

The following bash code can export a CPP file for project libfacedetection

cd $TRAIN_ROOT/tasks/task1/
./exportcpp.py -m weights/yunet_final.pth -o output.cpp

You can copy $TRAIN_ROOT/tasks/task1/ to $TRAIN_ROOT/tasks/task2/ or other similar directory, and then modify the model defined in file: tasks/task2/yufacedetectnet.py .
