Optimum value for scales Iris in Libor masek code for Recognition
Posted: Nov 15, 2012 12:30 AM

I am undergraduate student of EEE and interested in iris recognition and trying to simulate libor masek code.

what is the optimum value for 'scales' in
function. For different persons minimum hamming distance (hd) occurs for different 'scales' value. when i set a threshold value for 'scales'=1 or 5 more than one person is detected and sometimes false person is detected.

I have created template by [template, mask] = createiristemplate(eyeimage_filename)
for both left and right eye for 60 persons and saved the data in two mat file.
I create another template from individual left and right eye (i.e. person 50) and load the both mat file find out hd by hd = gethammingdistance (...) individually for left (hd_l) and right (hd_r) eye from corresponding database. Then
run
[C_l I_l]=find(hd_l<.30);

[C_r I_r]=find(hd_r<.30);

person=intersect(I_l,I_r)
