Question
Facial recognition for PHP
Hi,
I am interested in setting up facial recognition on a linux server, preferably something that can recognise faces at an angle, under different lighting conditions, different facial expressions, with/without glasses or facial hair.
Ideally it should be possible to generate a "faceprint" from an image that can be saved to a database for later comparison, so that when a compare is done we only need to find similar records in the database.
The idea is that we have 2 PHP scripts, the first will scan a directory of images and save the faceprints to the database, we can then delete these images. The other script will allow a user to upload an image, and then compare that image to the faceprints in the database, showing the top 5 closest matches in order of closeness.
I would also be interested in something similar that allows shape recognition, logos for example.
Is any of this possible, or am I being too optimistic?
Hope you can help,
Jim

I have had a look at OpenCV, but cannot get it to pass the post build checks (builds with no errors but the checks fail).
Unfortunately it doesnt look like it is capable of doing what I want it to do reliably anyway (at least not with my limited knowledge) so I am going to give up on this for now.
Thanks

Your getting into PHD thesis level stuff here and PHP is probably not going to be the best tool for you to use.
You can do some reading on different algorithms here: http://www.face-rec.org/al
Unless you have a degree (or are gifted) in CS or mathematics, you are probably being too optimistic.
You might be able to find something you could modify from here: http://pages.cpsc.ucalgary
Have fun!
