About

What is go-face?

go-face is an open-source Go library designed for face recognition, integrating with the powerful dlib machine learning toolkit. It enables developers to implement robust face detection and recognition functionalities directly within their Go applications. The library requires specific dlib and libjpeg development packages for compilation across various operating systems like Ubuntu, Debian, macOS, and Windows (via MSYS2). It supports the use of pre-trained models for face landmarks, human face detection, and face recognition, which can be downloaded from a companion repository. The tool offers detailed GoDoc documentation and provides clear examples for initialization, face recognition from images, and classification of recognized faces.

Best used for

Ideal for developers who need to add face recognition features to their Go applications, detect faces in images, and classify recognized individuals. Especially valuable for projects requiring robust, open-source biometric capabilities leveraging the dlib machine learning toolkit.

FAQs

What are the system requirements for go-face?

To compile go-face, you need dlib (version 19.10 or newer) and libjpeg development packages installed. Specific installation instructions are provided for Ubuntu, Debian, macOS (via Homebrew), and Windows (via MSYS2), ensuring compatibility across major operating systems.

Which models are required for go-face to function?

go-face requires three specific models: shape_predictor_5_face_landmarks.dat, mmod_human_face_detector.dat, and dlib_face_recognition_resnet_model_v1.dat. These can be downloaded from the go-face-testdata GitHub repository, which provides the necessary data for the library's operations.

How can I improve the accuracy of face recognition with go-face?

To enhance accuracy, consider using CNN recognizing, experimenting with different ClassifyThreshold tolerance values, and adjusting size/padding/jittering in NewRecognizerWithConfig. Providing more samples per category to SetSamples and implementing custom classification heuristics can also yield better results.
