how can i process this image in excellent way in order to extract veins from image exactly?

please if anyone can help me.

Interesting. Someone sent me the very same image earlier today and asked for "the complete matlab code for this Biometric Authentication Using Fast Correlation of Near Infrared Hand Vein Patterns algorithm". The last part of that sounds like the title of a paper to me, so if you are doing something similar you might want to see if you can find a paper on that topic.

[mmm ssss]

i have the same paper above ,but i try to find any other proposed methods that enable me to get better results.

do you understand me?

[mmm ssss]

are you give the person "the complete matlab code for this Biometric Authentication Using Fast Correlation of Near Infrared Hand Vein Patterns algorithm".?please inform me.

[Walter Roberson]

I am not sure I understand the question. If you are asking what my reply was to the person who emailed me privately, then really that is not your business unless you are that person.

i am very sorry if my question disturbed you.

But my target from question was only that if i can benefit from what you do for the person .

generally , i am sorry again.

[Walter Roberson]

I would estimate that you have progressed past the point where my reply to the other person would have been of benefit to you.

[mmm ssss]

i did not understand your last comment .

[Walter Roberson]

You asked if you could benefit from what I did for the other person. Please be assured that the answer is NO.

I will not be able to answer further questions as to what I did or did not tell someone else.

[mmm ssss]

i told you that i am sorry for my question.

Answer 1

[Sean de Wolski]

I'd start with my shrinkWrap function to segment the hand.

[mmm ssss]

how can i implement it in matlab

?

[Walter Roberson]

Sean already implemented it in MATLAB. Click on the "Download All" link in the upper right corner in order to download his code.

[Sean de Wolski]

Download, save it somewhere on the MATLAB path, read the instructions and run it on your image.

[mmm ssss]

thanks

i will understand the code,try to implement it on my image and informe you .

[mmm ssss]

i tried to run your code on my image ,but i failed .

any help?

[Walter Roberson]

What did you observe when it failed? Were there error messages?

[Image Analyst]

Shrink wrap won't find the veins, it will just give you the hand, which you could also get via simple thresholding.

[mmm ssss]

i can not implement it because i did not know how to do this ,is it can be implemented on my image at http://tinypic.com/view.php?pic=5wh0lg&s=5 or not? if it can be implemented what are variables i must change it in the code.

i am a beginner in Matlab

what are the solutions or steps you advise me to follow to obtain veins?

[Image Analyst]

It looks tough because even I can't say where the veins are. Even if I could, it's definitely a judgment call as to when the vein disappears.
