There are two biometrics specifically related to the nose:
- The shape of the nose
- The pores of the nose
Shape of the nose
(02 March 2010) Unlike other facial features used for biometrics, such as eyes or ears, noses are difficult to conceal and also aren’t changed much by facial expression. Dr Adrian Evans and Adrian Moorhouse, from the University’s Department of Electronic & Electrical Engineering, decided to investigate whether images of people’s noses could be used to recognise individuals.

Pores of the nose
Position of the pores from the nose can be used for recognition, as demonstrated by Song & als in 2009. A specific camera was used:
And the following preprocessing steps were applied to extract the position of the pores:
