Loading

• GazeDetectionEngine: The main class that utilizes various components to process the gaze detection.

  • FaceDetector: Detects faces in the input image.
  • GazeEstimator: Estimates the direction of the gaze.
  • HeadPoseEstimator: Estimates the head pose.
  • LandmarksEstimator: Detects facial landmarks.
  • EyeStateEstimator: Determines the state (open/closed) of the eyes.
  • ResultsMarker: Marks the results on the image for visualization.

• BaseEstimator: An abstract base class for all estimators.

  • EyeStateEstimator, GazeEstimator, HeadPoseEstimator, LandmarksEstimator: Inherit from BaseEstimator
