image processing - Marking fingerprint minutiae - Matlab -

-

i have project on fingerprint matching , got stuck on marking minutiae.
have binarized image, closed , thinned , have use crossing number find termination , bifurcation points. how mark them on image , store them? thanks!

you should bwmorph - function allows perform sorts of morphological operations on images. 

ep = bwmorph( bw, 'endpoints' ); %// returns mask "terminations" bp = bwmorph( bw, 'branchpoints' ); %// returns mask "bifurcations"

to coordinates of special points masks, can use find:

[epy epx] = find( ep ); %// x,y coordinates of endpoints.
