For the problem of the 2D-Gabor filter design,a method of single frequency 2D-Gabor filter design is proposed.The meaning of every parameter of 2D-Gabor filter in detail is analyzed,and the single frequency ω fit for the iris texture is found through dichotomy,and finally every parameter is chosen according to the relationship between ω.One 2D-Gabor filter in single frequency is designed.Experimental results show that when the proposed designed single frequency 2D-Gabor filter is used to perform feature extraction,the recognition rate could be above 98.61%.So taking advantage of single frequency 2D-Gabor filter not only can increase the speed of feature extracting,decrease memories but also can be convenient for hardware to realize.
