Face Similarity

This is a demo of a very early stage alpha-version of the software. Further developments and performance/reliability improvements will be published later so please check for future updates or newer versions.
Automatically detects two faces in front of the camera and gives a similarity estimate measure as a percentage value between 0 and 100.
It makes use of the back camera of the device. Use of the front camera (for selfie like comparisons) will be implemented in future versions.
If more than two faces are present the two bigger ones are chosen.
The app can be applied either to live human beings in front of the camera or to still pictures aimed at.
It adapts to size changes. It does not adapt for the moment to angles so faces should stare in the same direction.
It compensates light/illuminations intensity but for the moment not to light angles differences so the illumination conditions do not need to be excellent but need to be similar on the two faces (so either uniform or with same angles and/or with same diffusions).
Enjoy.
