I don't think there's any mention of NN to create those filters - in fact, not sure if it's ML at all. Very likely some off-the-shelf CV face-detection - especially considering it must run real-time on a phone.

You can trivially detect facial features using Deep Learning/CNN on a phone real-time. https://www.kaggle.com/c/facial-keypoints-detection https://www.kaggle.com/c/facial-keypoints-detection

Even the "simplest" face detection algorithms rely on strong machine learning concepts, eg: Viola-Jones uses AdaBoost to train the face classifier cascade.

    The opening paragraph in that page literally says: "[...] It is a machine learning based approach where a cascade function is trained from a lot of positive and negative images. [...]"
