shape / face detection in image ?

Copy linkTweet thisAlerts:

Hi all. Just wondering if this exists at all. It may not be in PHP.

Say I have thousands of pictures and I want to create thumbnails out of them. But I don’t want to simply resize the whole images, I’d like to crop them so it feathers around the person’s face.

So the script would have to detect the approximate area where a human face is found. Then draw a rectangle around the area, add 100 pixels to each side and crop that area.

I know it’s asking for much.. but maybe someone’s done this already and you know about it.. just going out on a limb here. If you know of a script, or a software that does this, please let me know!

@NogDogMar 28.2008 — I'm not aware of anything, but my guess is that if such a thing is available, it's probably done in C or other compiled language.
