MATLAB: How to compare different numbers of features in multiple pictures to find out similarities between fingerprints

Hello

When I extract fingerprint features, I get a different number of minutiae from each image.

How can I compare different numbers of features to find out similarities?

Thank you so much

K = randi(200,80,1);
out = reshape(K,[],8);
for i1 = 1:size(out,2)
    A = out(:,i1);
    i2 = 1;
    while numel(A)
        s = A(1);
        for j1 = 2:numel(A)
            if s > A(j1)  
                k = A(j1); 
                A(j1) = s;
                s = k;

MATLAB: List various image similarity features

There are literally thousands upon thousands of things you can measure about an image. No one can list them all. You have to say what you're looking for and measure only those things, and not waste time measuring the thousands of other things that you could possibly measure. For example, you could measure SSIM (<http://en.wikipedia.org/wiki/SSIM)>, PSNR, area fraction, length of your widgets, concentration of fluorescent dye, amount of radioactivity, number of people, speed of cars, equivalent circular diameters, morphometrics, volume of logs on the timber truck, quantity of heat emanating from the building, or countless other things.
