Minimum polygon inside an image; Hand Characterization;

[Belerophon]

Hey.
My problem is: I need to characterize a human hand (image).
So I intended to first get the PALM off the image, so I could get an image
with just the fingers. With just the fingers, it would be easier to get some measures of the them.

Convex hull of an image is somewhat standard. I was wondering if getting the smallest polygon inside an image (---> the hand palm) is also standard.

Does anyone know something written in Java to do this??

Thanks.

The smallest polygon? Wouldn't you want something like the largest convex polygon that is within the outline of the hand?

Ok...lol...my mistake.


I need the "largest convex polygon that is within the outline of the hand", that is the hand palm, so I can take it off the image.
