Requirements: python 3.12, numpy >= 1.21.

1. Install the package with a following command:

   python3 -m pip install mini-face

2. Download model data files (subdirectories /model/ and /AU_predictors/) from this repository or official OpenFace release. You will also need files from here.

Python usage

Below is a minimalist example of using the module from Python code:

   import cv2
   import numpy as np
   from mini_face import GazeFeatureExtractor
   from mini_face import PredictionMode

   if __name__ == "__main__":
      image = cv2.imread("test_image.jpg")
      extractor = GazeFeatureExtractor(
        mode=PredictionMode.IMAGE,
        focal_length=(500, 500),
        optical_center=(860.0, 540.0),
        models_directory="./model",
      )

       result = extractor.predict(image, np.array([0.0, 0.0, 1080.0, 1920.0]))

       print(f"{result = }")
