If you don't mind me offering help on regionprops. . . . .
Here is an image analysis demo that I've uploaded that exercises
bwlabel and regionprops and ismember in a very instructive way:

check the returned Eccentricity of the region; if the region is lips, the
eccentricty is likely to be different than if the region is beard shadow and
hallow. In the case of beard shadow and hollow, I would imagine that after
narrowing down to the _inside_ of that area, that you would run snakes again
and it should find the lips that time, I think.

Please read the commentary at the above URL: the problem is with a Mathworks
supplied file. You can edit that file yourself and change the sprint to sprintf
