Hi David,
fyio, to even better improve the localization of the face and to
filter out false positives I'd often use face detector in the
combination with the legs detector, e.g.
http://tum-ros-pkg.svn.sourceforge.net/viewvc/tum-ros-pkg/perception/people_detector_node/.
I did not check as of lately but I am pretty sure that Caroline also
has one in the people stack.
cheers, D.
