Simpler U-Net model outperforms complex attention models for InSAR phase unwrapping

A new paper challenges the trend of using complex computer vision models in InSAR phase unwrapping, demonstrating that a simpler U-Net architecture outperforms attention-based models. The study, conducted on a large InSAR dataset, found that the simpler model achieved significantly better accuracy and speed. This is attributed to the simpler model's adherence to the physical smoothness constraints of geophysical fields, avoiding the high-frequency artifacts introduced by more complex architectures. AI
