Face detection with PHP

Faces have a certain form and so it is possible to search for it. At
the end of the search you will say how many human faces are on the
image or better: Where are human faces on my image. This article is

The library is shipped with training files, what was trained with
hundrets of photos to detect faces from different perspectives on
images and so we can focus on the PHP part.

Some may ask, what is this good for? Google has added the opportunity
to search only for faces in their Image Search. Lets play with Google.
