shape detection with given patterns

edit

Hi,

I want to do the following task:

Given from specifc curves I wanna check if it fits into specific shapes. E.g.

I have sample shape of a 2D form of a bell, on which the perfect outline is drawn in black, and the outer margins in e.g. red. This shape is stored in a jpeg-file. Next I have a curve and want to figure out if that curve might fit into the shape of a bell, i.e. how good would it fit on the black line resp. how far away this is from the red-line....

To be honest, I haven't used OpenCV yet, I currently just evaluating my options.

If that approach would work, is there a limitiation to the language? i.e. can I use as well Java - or even Android? Or is it better to use Matlab????

Hints would be appreciated
