Janus: Multi-Task Head Pose Recognition Model

Model Description

Janus is a multi-class head pose recognition model that identifies key directional movements of the head. Named after the Roman god with two faces, Janus symbolizes different directions and perspectives. This model is designed for real-time applications such as gesture recognition, virtual meetings, and interactive systems.

Key Features

Framework: Keras
Model Type: Functional (with combined multi-task outputs)
Input: 468 facial landmarks (x, y, z coordinates) from MediaPipe
Output: Classifications for head direction, motion, and up/down movement
Tasks:
- Head Direction: Front, Left, Right
- Head Motion: Tilt, Turn
- Up/Down Motion: Up, Down, Unknown

Limitations

May not perform well on extreme or non-standard head poses
Optimized primarily for front-facing camera angles

Ethical Considerations

Use responsibly and avoid applications that could misuse facial data
Respect privacy and data protection regulations
