AI powered detection of age of face, body proportions and breast size

A large library of AI generated NSFW images needs to be analyzed and each image given scores to detect possible violations against the laws or policies, specifically detecting if images contain individuals appearing to be younger than 18 years or could be taken/mistaken for a child

I think a combination of the following criteria / scores will be useful:
1. facial age
2. body proportions age
3. breast size
4. child typical surrounding, clothes or features like school uniform, kids room, toys

A large library of over 3m images to train your model can be provided
