"FacialAge" (Built-in Classifier)

Estimate a person's age from a face in the image.



  • The classifier is applied to the largest face found in the image.
  • The classifier is based on the MobileNet Model Trained on UTKFace Large-Scale Face Dataset.
  • The classifier may download resources that will be stored in your local object store at $LocalBase, and that can be listed using LocalObjects[] and removed using ResourceRemove.
