Face detection in java

Question

Can anyone recommend a decent java library for face detection (recognition not required, just detection). The library would preferably be pure java (e.g. no dependencies on other native libs, DLLs or such). Platforms: Linux is a must; OS X and windows are very nice to have. Performance isn't a big deal, can be slow, it's for server offline processing. All I need to know is: are there faces in the photo? If yes, what are the coordinates of their bounding boxes? Thanks

Answer 1

There is an OpenCV binding for processing that could be used with pure java I think. But it depends on the OpenCV framework so its only a solution if you don't find anything else.

Answer 2

Check out Jon's Java Imaging Library which has face detection built in. You may have a little bit of work to do since it was originally written for J2ME but has a library for J2SE.

Answer 3

Look for Java implementations of Eigenfaces. The OpenCV binding is a real pain in java and a cross platform environment.

Answer 4

Faint (and sourceforge) apparently wraps OpenCV, but also have a pure java eigenfaces (detection). It is sadly GPL - I've recently asked whether they'd consider LGPL.

Here's OpenCV, btw. Wiki. "OpenWiki", since the former is closed. "Face Recognition using OpenCV" - apparently what Faint does. A guy that has used OpenCV and JNI, doing real time detection on a webcam.

Here's the Face Recognition Homepage's page about algorithms (academic papers, not java).

Finally, since I can't comment on other people's "answers", I'd like to know if @steven actually knows of any such library, or if he just, in effect, says "Google it, I personally have no idea whatsoever"??
