The Lord Lucan Doppelgänger
The BBC with Neil Berriman and Glen Campbell had tracked down an elderly 82 year old man to Perth Australia believing he was Lord Lucan. Various facial ID systems had been used to confirm he was Lord Lucan.
But if you test the doppelgänger with OpenCV he doesn’t match with himself from the 1960s. But that is normal. The age gap is too large and picture quality has a big impact.
Equally neither match with Lord Lucan.
But he was a perfect doppelgänger. When you create an average image of Lord Lucan and the ‘almost twin’ as a drag artist you get:
It is almost like they were twins separated at birth.
If you put the three images together you get:
The obvious answer for Neil to end his quest should have been to request a DNA sample.
Poor quality images fail to be scanned correctly. But improving them might be adjusting the position of facial landmarks.
You can test this yourself with my “draft” app:

This is a later draft to the image shown above.
In my software I am proposing a doppelgänger has a high landmark score but low descriptor score. I will verify with other images of doppelgängers. I am guessing that means they have near-identical skulls but different shapes of ears and nose. You can have big flappy ears versus tiny ears and landmark similarity remains high.
