looks like the unwrappong did not get over this low coherence border
What tile size did you use?
Intuitively, I would test if “SMOOTH” results in better unwrapping (instad of TOPO or DEFO) and also check if the progress wrks better
Maybe the water areas in the bottom are also a source of error. You might want to try with this proposed method on masking decorrelated areas: Is it the right way to create mask for phase unwrapping?
