YuNet

YuNet is a light-weight, fast and accurate face detection model, which achieves 0.834(AP_easy), 0.824(AP_medium), 0.708(AP_hard) on the WIDER Face validation set.

Notes:

Model source: here.
This model can detect faces of pixels between around 10x10 to 300x300 due to the training scheme.
For details on training this model, please visit https://github.com/ShiqiYu/libfacedetection.train.
This ONNX model has fixed input shape, but OpenCV DNN infers on the exact shape of input image. See https://github.com/opencv/opencv_zoo/issues/44 for more information.
face_detection_yunet_2023mar_int8bq.onnx represents the block-quantized version in int8 precision and is generated using block_quantize.py with block_size=64.

Models	Easy AP	Medium AP	Hard AP
YuNet	0.8844	0.8656	0.7503
YuNet block	0.8845	0.8652	0.7504
YuNet quant	0.8810	0.8629	0.7503

*: 'quant' stands for 'quantized'. **: 'block' stands for 'blockwise quantized'.

Demo

Python

Run the following command to try the demo:

shell

# detect on camera input
python demo.py
# detect on an image
python demo.py --input /path/to/image -v

# get help regarding various parameters
python demo.py --help

C++

Install latest OpenCV and CMake >= 3.24.0 to get started with:

shell

# A typical and default installation path of OpenCV is /usr/local
cmake -B build -D OPENCV_INSTALLATION_PATH=/path/to/opencv/installation .
cmake --build build

# detect on camera input
./build/demo
# detect on an image
./build/demo -i=/path/to/image -v
# get help messages
./build/demo -h
