fun=@minutie; L = nlfilter(K,[3 3],fun);

??? Error using ==> feval Undefined command/function 'minutie'. Error in ==> nlfilter at 58 b = mkconstarray(class(feval(fun,aa(1+rows,1+cols),params{:})), 0, size(a)); Error in ==> readimage at 38 L = nlfilter(bw2,[3 3],fun);

can anybody help me?

You do not have a function called "minutie" on your search path. Check your spelling. Or move that m-file into the same folder as your readimage() function.

By the way, read this http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup and fix your post.

Okay if u know coding for minuiae extraction then help me

I don't have any such code. You must have it. How did the line fun=@minutie; get in there? You must have written it or copied code that had written it. So either you or the code you copied must have that function. No one would have written that line of code otherwise - there's no reason to. So it must exist somewhere . Where is it? It's not built into MATLAB, I know that.

%THINNING K5=bwmorph(~K4,'thin','inf'); figure,imshow(~K5) title('Thinning') set(gcf,'position',[1 1 600 600]);

fun=@minutie; L = nlfilter(K2,[3 3],fun);

%% Termination LTerm=(L==1); imshow(LTerm) LTermLab=bwlabel(LTerm); propTerm=regionprops(LTermLab,'Centroid'); CentroidTerm=round(cat(1,propTerm(:).Centroid)); imshow(~K) set(gcf,'position',[1 1 600 600]); hold on plot(CentroidTerm(:,1),CentroidTerm(:,2),'ro')

I have problem in the second part

Please format. Read this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

Getting back to your original question, is it possible you misspelled the term. You have "minutie" - is it possible you should have said ""minutiae?

[preethi]

No that is not a pro

[Image Analyst]

Not sure what that means. Presumably it means that you have not misspelled anything. So then we get back to my original answer which is that you do not have a function names that anywhere on your search path. Why do you think you should?
