Isocurves label and coordinates

[Ruben Padial]

Hello,

I'm displaying a picture with its level curves (isocurve). I based my code in Isocurves example but I have 2 additional goals:

1. Plot at the same tiema a label each isocurve. Find an example below
   
2.  To get a list with the coordinates (xi, yi) of each isocurve
   

Do you have any suggestion? Thank you in advance.

I can answer the second question. There is a pyqtgraph function called isocurve 

that can calculate them:

There is another function in skimage that is doing the same thing:

cheers,
