Let's talk about face alignment
In Bob we have a 10 years old standard for face-alignment; in short we geometrically normalize the face using a set of affine transformations using the eyes as reference.
Some packages (like the face zoo and the deep-insight) does a very similar job, but with an automatic landmark detector on front. As far as I could see, they have a code to find the best affine transformation to match the automatically detected landmarks to 25 reference points of the face.
Any thoughts on that?
Shall we put this in place?
I think this analysis of alignment makes at least a small report (if not a conference paper).
