Hi all,

I am doing image analysis and now I am facing a problem that I'm not
sure how to tackle, hopefully someone of you can give me some hints on
how to proceed.

I have a wireframe model of a face (a set of 2d points and the
connections between them, let's call it "the model") and, on the other
hand, I have a set of point coordinates (corresponding to facial
features in a face image, call it "the feature set").

The two sets don't match, actually the model has got a number of points
that is the double of the ones contained in the feature set.

Could anyone of you please give me some hints on how to match the two
models? I mean, what is the best way for modifying the position of the
points in the model that don't have a corrisponding point in the feature
set? Any papers worth reading?

Thanks a lot!
