Polar Rose: photo tagging using face recognition, Flickr, and Facebook

Polar Rose, a Swedish startup, offers a photo tagging service. The user names a person in a photo and face recognition is used to suggest other photos that might contain the same person. The service synchronizes with Flickr to access the user's photos and with Facebook to obtain the names of friends of the user. The latter feature is used to provide an autocomplete feature to save typing. The service is free.

Polar Rose also allows users to optionally send notifications to people who have been named in a photo, and to optionally receive such notifications.

In addition to Malmo, Sweden, Polar Rose has teams in Warsaw, Poland and San Francisco, USA.
