Face Age

Analyzes and predicts the age of a face in a video stream. The face age is predicted within an age range. The event listener continuously obtains the data in a JSON object as FaceAI analyzes the age of a face. If the prediction quality is poor, the event is not issued.

Method

To start or stop analyzing the age of a face.

• Class: EnxFaceAI
• Method: public void enableFaceAge(boolean enable)

Parameter

• enable : Boolean. Set it to true to enable or start analyzing the age of a face. Otherwise, set it to false.

Callback Method

• onFaceAgeData : This method is received repeatedly with the Face Age Analysis report as a JSON object.

JSON Object: Received with Face Age Analysis data.

{	output: {
		age: {
			-18: Number, 
			18-35: Number, 
			35-51: Number, 
			51-: Number
		}, 
		numericAge: Number
	}
}

Analysis Data Explanation

• output : Face Age Analysis Report
  • age : Filtered (smoothened) age prediction:
    • -18 : Probability Weightage suggesting less than 18 years old.
    • 18-35 : Probability Weightage suggesting between 18 to 35 years old.
    • 35-51 : Probability Weightage suggesting between 18 35 years old.
    • 51- : Probability Weightage suggesting equal or greater than 51 years old.
  • numericAge : Numeric. Estimated Age

Note: In case of poor quality of the prediction, the event is not fired (that is, it is skipped for the specified frame).
