I am working on retinal identification system. I have to calculate false rejection rate and false acceptance rate. And then plot them according to different threshold. Threshold value of '8' is found to be suitable for my images. The images having value less than 8 are intruder and images with threshold 8 are authenticated. Can anybody help me how to find FAR,FRR and then plot them accordingly in Matlab?
