Brief description:
The Gaze Engine is a software library designed to estimate and visualize a person's gaze direction. It processes video frames to detect faces, analyzes facial landmarks to determine head pose and eye direction, and combines these to calculate a final gaze vector. The engine relies heavily on OpenCV and various filtering techniques for smooth and stable results.

(Related projects: Driver Monitoring, Driver Fatigue Detector, Driver Distraction Detector, Head Gaze Tracker, Eye Gaze Tracker)

Capabilities of this solution:

1. Detection of faces in camera feed.

2. Tracking and re-identification of faces, each associated with a unique ID.

3. Placement of facial and eye landmarks.

4. Estimation of eye openness.

5. Calculation of the head direction vector.

6. Calculation of the eye gaze vector.

Explanation:

1. Normalised and rotated image of the right and left eye, showing iris and pupil segmentation

2.a. Head direction vector in Euler angles

2.b. Visual representation of the direction of the head

3.a. Vector of the eye direction in Euler angles. Roll is meaningless for the eye, so the demo does not show it. Also, the demo only calculatesthese angles for the right eye now.

3.b. Visual representation of the direction of the eye

4. Openness of the right and left eye (normalised values, min:0 - max:1)

5. Running speed of demo
