detecting location on a image

Postby pkhurpade » Mon Jun 28, 2010 2:22 pm

Hi ,

I have an image on screen. I have to identify what part of image is located after tapping at particular point on screen.
e. g. I have an image of Face on screen. Now if i touch at location of eye, it should identify that i have touched eye.

I will get the x,y co-ordinates but how shall i detect that those co-ordinates belong to location of eye in a whole image?

Thanks,
Prashant

If you find the solution to this you'll probably have a millionaire technology in your hands :P

Do you already know what images will be loaded onto the screen so that you can pre-determine the location of the features?
