Face Detection in Historical Photos
As an experiment in my Genealogy research, I started using Machine Learning (AWS Rekognition) to scan public historical photos (from Flickr and Reddit public albums).
So far, the PoC contains about a million faces from a bit over 400.000 images.
Eventually, the idea would be to integrate the system into tools such as Geni or MyHeritage and use it as automatic hints to find existing pictures or known people (based on know portraits).
