USING FACE RECOGNITION
5 By default, the system will start searching through and
indexing your entire picture library but you can set it to
just look in one particular folder. While the search is running, go
to the Folders tab and select the folder that you want to search.
The system will immediately begin indexing that folder and any
sub-folders that it contains.

As the system starts finding faces, you can start adding
names to them. At first, obviously, it won’t recognise
anyone and the faces will just have question marks under them.
Click on the question mark to add a name to the face and the
system will then start suggesting similar faces to the ones that
you’ve identified.

Although the face recognition algorithm is extremely
good, it’s really only identifying patterns of pixels that look
like a face, so it will sometimes make mistakes. Statues, posters
and cats (although not dogs, strangely) will confuse it, as will
other face-like shapes. You can remove these by clicking again
on the right-hand button.7 Once you’ve added a few names and the system starts
making identifications, you can confirm the correct ones
by clicking on the Tick button under the thumbnail. The more
correct identifications that you confirm, the more accurate the
face detection algorithm will become. You’ll be surprised by just
how accurate it can be.
10 You’ll be amazed at how successful the face recognition
can be. It can easily recognise photos of people taken
thirty years apart and has no problem with sunglasses, fancy
dress costumes and people pulling silly faces. The mistakes can
be quite amusing too, a depiction of Satan on a poster mistaken
for a former boss, for example!8 Similarly, if the system makes an incorrect identification,
click on the button on the right below the thumbnail to let
it know that this is not the person it thought it had recognised.
The suggested name will revert to a question mark, so if it is
someone you recognise you can click on that and enter the
correct name instead.http://www.bdmpublications.com 53
