hey..this code just enhances the fingerprint..

I = imread('fingerprint (16)--ii.png');
figure,imshow(I)
I1 = rgb2gray(I);
figure,imshow(I1)
I2 = im2bw(I1,0.23); // here i have selected 0.23 as my level.. u can select a level based on the entire picture colour
figure,imshow(I2)
I3 = imcomplement(I2);
figure,imshow(I3)


i have used this code to enhance fingerprints on a dark background..
if this doesnt work..try using edge detection and other threshold functions..
i have also added my first input image..and my final image..!!
