Mytton you are such a joke. Your morphs do NOT track facial features, otherwise, explain how the algorithms work smart guy. Morphs are a fade that use edge detection and high pass filters to smooth the transition between frames. But rest assured that every intermediary frame is BULLSHlT and useless for analysis! But you are just a wannabe photo-analyst that found the Morph button on your GIMP app. Otherwise, you know squat about how any of this works. So STFU because you are out of your league and a disservice to the JFK Forum.
Here we go again, Mr Photogrammetrist/Physicist/Nuclear Scientist/Astronaut and all round Schlub to the rescue! Hooray!
The reason why the morphing comparison works so effectively is the intermediary frames, by definition the mathematical relationship between two identical objects remains constant when photographed from any direction and when these images are combined every point in each three dimensional object in each corresponding frame displays this same identical relationship, thus when two objects are identical we have a smooth rotation whereas when two objects are not alike we don't.

Wtf? As I said you really don't have a clue!
Here's two images of two faces, are they the same person?
Your simple method of fading yields crap.
Whereas when scientifically morphed the spatial relationship between millions of pixels is constant and we see that it must be the same person.
