MTCNN is one of the best face detection algorithms. Here is inference only for MTCNN face detector on Tensorflow, which is based on davidsandberg's facenet project, include the python version and C++ version. The project is written primarily in C++, distributed under the MIT License license, first published in 2017. Key topics include: arm, arm64, cpp, face-detection, facenet.

C++

There are two version for C++.

One is to be build inside tensorflow code repository, so that it needs to be copied to the directory tensorflow/example.
please check cpp/tf_embedded/README.md for details.

The other is the standalone one, just needs libtensorflow.so and c_api.h to build and run.
Please check cpp/standalone/README.md for more details

Python Run

install tensorflow first, please refers to https://www.tensorflow.org/install
install python packages: opencv, numpy
python ./facedetect_mtcnn.py --input input.jpg --output new.jpg

Build tensorflow on arm64 board

Please check out the guide how to build tensorflow on firefly
