While working on emotion detection, I came across a number of techniques such as using ASM, SIFT etc. All the techniques have assumed that I have all the landmark points (points on my eyes, nose, mouth etc) already detected. I am unable to figure out, how do I locate these points on image of face.

I can locate face and mark features such as eyes, mouth, nose using cascades but point landmarking (having points represent your eyes and so on) is something I am unable to understand. Any document to help me out with this!

Do this libraries directly help me mark the landmark points? I want to understand how does landmarking work basically and implement it myself if thats possible.

For example, check the thesis for flandmarks: ftp://cmp.felk.cvut.cz/pub/cmp/articles/uricar/Uricar-TR-2011-05.pdf Very well explained
