With my team we are pursuing our ML4Science project and we are encountering a problem. With an Unet model we obtained from satellites images binary masks that are supposed to represent the edges of the rooftops. For our next step, we have been asked to "polygonize" our masks. In other words we need to transform a mask into a set of vertices and edges. Has anyone any idea where to start our research?
this one seems to be pretty much what you need:
