摘要
为了提高指纹识别速度,在分析了Gabor滤波器实部特征的基础上简化了求二维卷积的运算,从而改进了Gabor滤波器算法,实验表明该改进算法使运算的复杂度由O(n2)降至O(n)。
In order to get a faster algorithm of fingerprint identification, by analyzing the properties of the real part of Gabor filter, the calculaiton of two-dimentional convolution was simplified. Experimental results show that the algorithm decreases the computational complexity from O ( n^2 ) to O ( n ) .
