I keep a reusable bag in the car boot for when I'm buying a few groceries or similar. I should estimate I've bought around ten of the bags at different times, but they seem to disappear of their own accord, long before they've worn out. So today I bought yet another one to restock the car. It also gave me an excuse to experiment with Apple's new iPhoto face recognition software.
I noticed that iPhoto lets you access an Aperture library, which is where I keep my photos stored. I grabbed 2-3 folders of maybe 100 pictures with a few consistent faces, taught the names to iPhoto and it then ran through the pictures getting the names mainly right. It missed a few but didn't guess any incorrectly.
Hmm, I thought, maybe it uses shapes and dates. So I then tried it with the ladybird on the shopping bag. I taught it the name and showed it 4 almost identical photos of the ladybird. It didn't have a clue. So it seem that the Face recognition isn't going to be fooled too easily with alien shapes.
My next experiment will be with the new ironic film soundtrack loops available in Garageband.
