Thanks, I will give it a shot! Although I guess the different targets do overlap since we have three classes: Roof Edge, Roof Corner, Roof Footprint. Some of them do share a part of the same pixels since corners are contained within edges and everything is contained inside the footprint. Will there be issues with your current proposed approach? What is another possible approach to overcome overlapping targets?
Tried to merge them to visualise them: https://i.imgur.com/TiVULYL.png 3
I guess I can make 3 separate binary segmentation models but I am pretty sure that it’s not better.
