This repository is a fork of the primary repository with minor modifications to run on Raspian Buster and Ubuntu 18+ with OpenCV. The Open Horizon service face utilizes this repository to build Docker containers. Please refer to the Dockerfile for details.
OpenFACE is an open source face detection library written in C++. The library analyzes images and video streams to identify license plates. The output is the percentage probability for any faces detected.
Outside of use in building the face service, see the original for instructions.
sudo apt update -qq -y && sudo apt install -qq -y git cmake build-essential imagemagick curl jq libopencv-dev
git clone http://github.com/dcmartin/openface.git
cd openface
mkdir build
cd build
cmake ..
make
✋ Remember to specify http://github.com/dcmartin/openface.git as the repository.
OpenFACE includes a command line utility: detect-image-demo.
After successfully building the face executable use the shell script faceanno.sh to annotate the original image with all detected license plates, for example:
% cd example
% identify people.jpg
people.jpg JPEG 377x250 377x250+0+0 8-bit sRGB 35090B 0.000u 0:00.000
% ../build/detect-image-demo people.jpg

The script requires ImageMagick and jq software; to install on Debian LINUX:
sudo apt update -qq -y && sudo apt install -qq -y imagemagick jq
Use the the shell script to annotate the image; for example:
% cd example
% ../build/detect-image-demo people.jpg > people.json
% ./faceanno.sh people
people-face.jpg
Releases are based on Semantic Versioning, and use the format
of MAJOR.MINOR.PATCH. In a nutshell, the version will be incremented
based on the following:
MAJOR: Incompatible or major changes.MINOR: Backwards-compatible new features and enhancements.PATCH: Backwards-compatible bugfixes and package updates.
