Rotation angle

[Lucifer1002]

Hello, I would like to ask, when COTR extracts the common view area, for some scenes with too large rotation angle, the formula area cannot be extracted. What is the possible reason for this phenomenon?

Hi, we tested the common area with different angles, and indeed that when rotation angles increases, the performance decreases. One possible reason is that we didn’t do data augmentation during training, and the trained network is not robust to in-plane rotation.
