Recognizing the contour of a drop from an image

Hi everyone!
I need to use libraries that allow me to recognize the contour of a drop from a photograph and create a set of 2d points from it. They have to be free software.

Do you know if there are any of them? It would be nice if they worked in C, C++ or Python.

Thanks in advance!
