Face Pose

Analyzes face rotation and position of a face in a video stream. The event listener continuously gets the data in a JSON object as FaceAI detects face rotation in a video stream. The face rotation angle data is represented in terms of radiants as Pitch, Roll, and Yaw.

Method

To start or stop analysis of face rotation and position in a video stream.

• Class: EnxFaceAI
• Method: public void onFacePoseData(String type, String value)

Parameters

• enable: Boolean. Set it to true to enable or start the analysis of face pose. Otherwise, set it to false.

Callback Method

• onFacePoseData: This method is received repeatedly with the Face Rotation & Position Analysis report as a JSON object.

JSON Object: Received with Face Rotation & Position Analysis data.

{	output: {
		pose: {
			pitch: Number, 
			roll: Number, 
			yaw: Number
		}
	}
}

Analysis Data Explanation

• output : Face Rotation & Position Report
  • pose : Filtered (smoothened) pose rotation angles expressed in radiants as pitch, roll and yaw.

Note: The maximum and minimum ranges for rotation angles are currently limited to +- (Pi/2) in radians, corresponding to +- (90°) in degrees, for each of the 3 axes. The zero point is when a face looks straight at the camera.

Sample Code

enxFaceAI.enableFacePose(true);		// To start analysis
enxFaceAI.enableFacePose(false);	// To stop analysis

// Callback
@Override
public void onFacePoseData(String type, String value) { 

}
