Facial semiology with AI: how I prepare teaching images with Gemini and MediaPipe

In my naturopathy courses, I teach facial semiology. It is an old, subtle practice that demands precise visual supports. I used to spend evenings hunting for royalty-free photos, drawing annotations on top, redoing them when the quality did not hold.

Today, I have a pipeline that generates plates in minutes. A teaching image, clean, annotated in the right places, usable in class or in an article. Nothing has replaced my teaching, but the preparation of supports has moved into a different world.
