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 data in a JSON object as FaceAI analyzes the age of a face. If the prediction quality is poor, the event is not issued.

Methods

• EnxFaceAI.startFaceAge(config, callback) : To analyze and predict face age in a video stream.
• EnxFaceAI.stopFaceAge(callback) : To stop analyzing and predicting face age in a video stream.

Parameters

For Method: EnxFaceAI.startFaceAge(config, callback)

• config : JSON Object. This is to configure or customize parameter using which the Face Age would be analyzed.
