Iris Patterns Extraction Technology Using Gabor Function
Liu Wang-jun · Information and Electronic Engineering · 2006
In order to extract the iris patterns from an eye picture quickly and conveniently,the Gabor function which is formerly used to simulate the simple cells in primary visual cortex is adopted as an eye picture filter function.Through analysing and optimizing the related function parameters,this method can distinguish the iris texture from sclera texture,and distinguish the iris texture from the pupil texture much better.Therefore the iris texture extraction can be implemented conveniently.The procedure of the iris recognition system are be simplified,as a result,its processing speed can be improved.
