Could someone please point me to the right direction?

I am able to initialize multiple contour widgets on my image, however,
I want to use only a single contour_callback. Currently, I am not able
to let the callback determine its caller contour_representation
automatically!

Any help will be highly appreciated.


Thanks,
Prathamesh
