Head Pose Estimation

This model detects all the faces in an image, then takes each detected face as an input to analyze the pose of the head based on the data obtained through a face detection system. It uses facial landmark models, such as eye corners, nose tip, and/or face appearance models.

Input type

For the input image, the following extensions are supported: JPG, JPEG, and PNG. The maximum image size is 1920x1080.

Result example

[
    {
        "probability": 0.9999996423721313,
        "rectangle": {

            "bottom": 350.8455882774045
        },
        "direction": {
            "yaw": 0.9754817470297894,
            "pitch": -1.840920759566032,
            "roll": 0.9923179751837665
        }
    }
]

Result interpretation

The output is a list of dictionaries that include the coordinates of all the faces and the probabilities of detection.
The location of the detected face is presented as the top-left and bottom-right pixel coordinates of the frame.
In the corresponding dictionary of a face, there are values for yaw, pitch, and roll angles for each detected face.
