about the "fusion.py" ---self.corner_points_feature

[Qiyz1]

Hello, I would like to ask what is the purpose of the corners_points_feature function in fusion.py, I didn't find any call about him, the code still works fine even though I intentionally changed the number of channels in it so that they don't work properly, what is the significance of him please, could you please reply to me below when you have the time, thank you!
