I would like to use Multiscale Combinatorial Grouping for my PhD research. However, I am restricted to use open-source implementations and this one runs on Matlab.

Does anyone know of an equivalent contour detection method that works on large images that is implemented open-source, preferably in Python?

Here some more background info. Equivalent methods would be:

I am interested in detecting contours of visible objects in drone imagery with a resolution of 2-5cm per pixel and extents of up to 1kmx1km for the purpose of automating cadastral mapping. Here an example of what the contour detection output should look like:
