Using facial recognition on Google Images
On Google Images is a new unofficial feature that lets you restrict searches to certain categories of precise images. For now appears to be available for options to search images containing faces or relating to news and events.
If we take for example the results provided by Google Images looking for the word "Paris", we can see that some are related to the city of Paris and others to Paris Hilton. Let me now turn to activate the option to restrict results to only images containing faces adding "& imgtype = face" at the end of 'URL: get as a result only of images containing human faces and mostly on (in this applicable) to Paris Hilton.
Instead adding all 'URL search parameter "& imgtype = news", it appears that Google applies a criterion such that returns results only images posted on news sites such as BBS or the New York Times.
You can have fun trying many other words to see in which cases the results differ more, I personally found interesting do the three types of research (standard sides, news) with the word "firefox".
