The abundant structure and streak feature of iris image can be used as personal identification.This capacity is more reliable than other biometric characteristic recognition.A iris recognition system is based on four parts: iris image sampling,iris image preprocessing,feature extraction,iris image matching and recognition.An iris recognition approach based on image Knn classifier is presented in this paper.The preprocessing includes location,normalization and enhancement.After that,the iris streak feature will be extracted by Gabor filter and the feature will be used in iris image matching by Knn classifier.Its results show that the method is feasible and prior to others.
