Sophie Robehmed, a freelance journalist is searching for her own doppleganger, using the power of the internet, social networking, like twitter and facebook, doyoulooklikeme.wordpress.com, etc. It seems like Google’s neural network based image search (search link for above image) (search with alternative image)
is not able to provide this functionality as yet.
The image search is able to find other copies of the original flyer, or lots of pictures with women with brown hair, pictures of people with surrounded by similar colours as the image you are searching with… I guess that is pretty impressive but not doppelganger level yet. I guess this is to be expected since it is image search, not face search. I think better software is available for face matching. I think there is software available for automatic tagging of pictures (facebook would make a good database for training your neurons!).
