The project is 'implementation of virtual mouse using hand movement'.Basically a webcam will be used to take the image of the hand in real time and the movement of the hand will simulate the cursor movement.
I am using the convex hull method

After application of the convex hull an area of the hand is formed with the peak points representing the finger tips.so how do i find the coordinates of the fingers?

I just want to say that finding the blob and its convex hull is next to nothing compared with fingerprint recognition itself. This topic is way too complex. I doubt you could get help in just the Quick Answer on this forum, unless you use some available library or other product for the fingerprint recognition...

i am not going for finger print recognition..its for the implementation of virtual mouse.after i detect the index finger i am thinking of using the robot class to track the movement of the hand

Do you mean detecting the location of the finger on a touch-sensitive screen? Then your question was extremely confusing. You really need to explain your problem in sufficient detail and much more clearly. If my guess is correct, this is much easier problem. But now, if this is the case, and if you already got a convex hull, the problem is almost solved already. What's your problem now?

I will be using a web cam for the image acquisition and i need to determine the coordinates of the index finger so that the hand movement can be tracked.what i want is that the mouse cursor should move in accordance with the index finger coordinate.i hope i am being clear enough?

This makes even bigger difference... I can only repeat: you should have told all that in first place.

Will you do yourself a big favor? You should have told all your detain in first place.
Use "Improve question" above and explain it all in one place in sufficient detail.
