The rules between discriminating index and Gabor filter parameters are revealed in this paper,such as frequency,direction,scale factor.In addition,it analyzes parameters effect on the performance of iris recognition system and proposes a new method to design the two-dimensional Gabor filters parameters.By deformation correction and rotation angle compensation,iris texture under head rotation,zoom and off-angle conditions can achieve accurate iris accurate registration.Iris location based on ellipse fitting method is used to improve the robustness and accuracy of iris segmentation.The iris recognition system is tested and evaluated using iris image database THP-Iris V1.0.Experimental results show that discriminating index of the proposed system is 7.64 and Equal-Error-Rate is 0.064%.
