In case if anyone is interested, publicly known face recognition algorithms usually require a photo to have at least 50 px between eyes. The article says that the system used by police has 90% error rate and this is surprisingly poor result. For comparison, an article about Russian photographer [1] says that he managed to recognise approximately 70% of people he took photo (he was recognising people in the subway to show how different people look in social networks and in real life; useless research in my opinion). If you would like to check it for yourself, you can try demos like searchface [2] - it has indexed most of the photos from the popular social network vk.com. I think the laws should be adapted to make face recognition illegal. Otherwise businesses and governments will want to be able to identify the citizens or customers, to collect and sell detailed data about them.
