how i short out from this.please help me.

%% EXTRACT FEATURES FROM AN ARBITRARY FINGERPRINT

error showing:

[Geoff Hayes]

indrani - what is the full error message? Please copy and paste all of the red text (from the error) to this question. And where did you get the code for ext_finger? Is it from https://www.mathworks.com/matlabcentral/answers/281914-i-have-a-fingerprint-recognition-code-in-matlab-in-which-for-which-i-want-detail-explanations-all-t?

[indrani dalui]

Dear sir ,here is the error message.from a file.actually this code downloded from internate,

Error in ext_finger (line 44)

[ binim, mask, cimg, cimg2, orient_img, orient_img_m ] = f_enhance(img);

Error in main_single (line 7)

ffnew=ext_finger(img,1);

[indrani dalui]

yes sir,this is the code:

https://www.mathworks.com/matlabcentral/answers/281914-i-have-a-fingerprint-recognition-code-in-matlab-in-which-for-which-i-want-detail-explanations-all-t?

[Geoff Hayes]

indrani - you still haven't posted the full error message. I suspect though that it is something along the lines of "Undefined function or variable 'f_enhance'" which is a function that you probably need to request from the author of he code that you found at the link.

[indrani dalui]

sir,

this the total error message

Extracting features from E:\Simple_FingerPrint_Matching\FVC2002\DB1_B\101_1.tif ...

>>> enhancement Undefined function or variable 'fft_enhance_cubs'.

Error in f_enhance (line 20)

enhimg = fft_enhance_cubs(img,6); % Enhance with Blocks 6x6

Error in ext_finger (line 44)

[ binim, mask, cimg, cimg2, orient_img, orient_img_m ] = f_enhance(img);

Error in main_single (line 7)

ffnew=ext_finger(img,1);

>>

[indrani dalui]

sir ,i also attached the f_enhence.m file

[Geoff Hayes]

So you are missing the function fft_enhance_cubs. Where did you get f_enhance from? Presumably the two functions (and maybe more?) would be together.

[indrani dalui]

sir,please guide me what should i do?

[indrani dalui]

dear sir ,

under a FExtraction file, so many m file are there.also attached the fft_enhence_clubs here.

[Geoff Hayes]

indrani - you have to make sure that this file (and any others related to this work) can be found in the MATLAB Search Path. Since f_enhance can be found, then make sure that fft_enhance_cubs is in the same folder.

[indrani dalui]

Dear sir,

when ,i was run this program the command window gives the result like this.i created a database there are only 8 fingerprint image,i saved.and but smilarity mathiching result look like this.sir please help me and guide what should i do.
