Hi,
I tried to generate genuine and imposter scores, in purpose to evaluate my iris dual authentication system (Multimodal biometric system). Following is my first trial on coding using Matlab:
Well, I obtained insatisfed result (I thought that form curves are gaussian).. see Figure
Thank's in advance ....
I tried to generate genuine and imposter scores, in purpose to evaluate my iris dual authentication system (Multimodal biometric system). Following is my first trial on coding using Matlab:
Code:
load('optimistic.mat');
xcut = 0.05:0.05:0.8;
GAR=100-FRR;
sigma1 = std(GAR);
mu1= mean(GAR);
pdf1 = normpdf(GAR,mu1,sigma1);
sigma2 = std(FAR);
mu2= mean(FAR);
pdf2 = normpdf(FAR,mu2,sigma2);
figure(1),plot(xcut,pdf1,'r',xcut,pdf2,'b');grid on;xlabel('Normalised threshold');ylabel('Frequency');legend('Genuines','Impostors');Thank's in advance ....
