dlib-face-recognition

Inspired by a similar python library, dlib-face-recognition is a Rust library that binds to certain specific features of the dlib C++ library.

This repository will dedicate itself to improve the library's content.

These include:

• An FHOG-based face detector.
• A CNN-based face detector (slower, but more powerful).
• A face landmark predictor for identifying specific landmarks (eyes, nose, etc) from face rectangles.
• A face encoding neural network for generating 128 dimensional face encodings that can be compared via their euclidean distances.

Original Working

The original work is here (unmaintaned; since Aug 2021).

Building

Supported Platforms

• Linux { aarch64, x86_64 }
  • Ubuntu 20.04
• MacOS { aarch64, x86_64 }
  • Apple Silicon (Apple M1)
• Windows { x86_64 }
  • Windows 10

For better maintenance, please let us know whether the other platforms support it. Besides, you may claim us whether the specific platform should support it through Issues .

Dependencies

• cmake
• Blas
• Openblas (optional; overrides blas for better performance when enabling openblas feature )
• dlib (optional; can be skipped by enabling build-native feature)
• lapack

For Windows, vcpkg may help building both Blas and lapack . For other platforms such as Linux, package managers should support installing them.

Building Native library

dlib-face-recognition requires dlib to be installed. You can either provide a existing system-wide installation, or build it with this library.

• To build it in compile-time:

  • cargo build --features build-native
    

• To use a system-wide dependency:

  • cargo build
    

The C++ library dlib will be installed via dlib-face-recognition-sys when the build-native feature flag is enabled.

For the build, this library uses cmake , so please make sure to have cmake .

The build-native flag is disabled by default, offering increased build times.

Building Rust package

dlib-face-recognition includes a embed-all feature flag that can be used with cargo build --features embed-all .

embed-all will enable the Default::default implementations the matching structs. These will search for the /files folder, and if a file doesn't exist it will be downloaded at runtime.

• CNN Face Detector: http://dlib.net/files/shape_predictor_68_face_landmarks.dat.bz2
• Landmark Predictor: http://dlib.net/files/mmod_human_face_detector.dat.bz2
• Face Recognition Net: http://dlib.net/files/dlib_face_recognition_resnet_model_v1.dat.bz2

It is recommended to acquire the files before compile/runtime and set them in a protected location. The embed-all flag is disabled by default, offering increased build times.

Testing

There is one included test to recognize, and draw a face's points:

• cargo run --features embed-all --example draw -> To run the example.

There is two files to benchmark the code, and test some functions:

• cargo test --features embed-all --test benchmarks -> To run the benchmarks.
• cargo test --features embed-all --test utilities_tests -> To run the utilities tester.
