Skin Texture Analysis
Another emerging model is Skin Texture Analysis. It uses visuals of human skin.
The system can catch vicuals from digital photographs and scanned images. Every human being has unique spots, lines and patterns. This system mathematically modelling all of them.
Surface Texture analysis is using same principles with the face recognition. It is taking a photo of a part of skin which is called skinprint. These photograph is divided into little blocks and then analyzed with this algorithm. Then mathematically modelled, saved in measurable space. System recognized all the pores, lines and image of skin texture. So it can even distinguish identical twins which is impossible with face recognition.
Tests show that adding skin texture analysis into face recognition system increases system success by %20-25 ratio.
