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.

Richard C Bishop 26-Mar-13 12:33pm

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.

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 26-Mar-13 13:48pm

There are rarely fungus on fingerprints :)

ZurdoDev 26-Mar-13 13:55pm

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.

Zoltán Zörgő 26-Mar-13 13:24pm

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: http://fewtutorials.bravesites.com/tutorials

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.

dieselc 26-Mar-13 21:25pm

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