I just want to know about how to identify the fingernails by image processing?
I'm trying to do a project for detecting the fingernail fungus,before that I want to know how to detect the finger tip(nail)

What are fingernails?

Those things on the tips of your fingers that you chew on? :)

I surely hoped the OP wasn't actually asking about that.

You never know.... I have seen some really strange "questions" of late.

This is true indeed. I try to keep some faith sometimes though.

1) Find the fingers.
2) The fingernails are on the sharper end.
 
This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.

What have you tried? Who on earth would want to identify fingernails?

It does not seem trivial at all, and it is not the computer science only. Do you have any research on the fungus appearance?

I'm hoping you meant fingerprints and in that case there are tools to do it. Just search online.
Zoltán Zörgő at 26-Mar-13 13:48pm
   
There are rarely fungus on fingerprints :)

You're right. I didn't actually read the whole body of the message. I jumped to the conclusion that the title was wrong, but I was wrong. :) Fungus it is.

As SA Sergey mentioned, it seems not trivial at all. Finding fingernails is one task, detecting fungus is an other. I have only suggestions for the first one. I suppose you can use Haar Cascade to find fingernails - you can train OpenCV cascade.
Choosing OpenCV (more preciesely EmguCV) is a good starting point.
Some tutorials, you might find of use:

Just a note for the fungus detection: it might be interesting to take and analyze photos taken under IR, UV and polarized light too.

You should post this as a solution.

OK. Thanks.

thanks for your replies, I'll go with the Haar Cascade
