May I ask the specific meanings of each parameter?

dict(type='RandomOBBRotate', rotate_after_flip=True,
     angles=(0, 0), vert_rate=0.5, vert_cls=['roundabout', 'storage-tank']),

May I ask the specific meanings of each parameter,especially 'vert_cls'

rotate_after_flip is a flap indicating the order of OBBRandomFlip and RandomOBBRotate. It changes the action order in MultiScaleFlipRotateAug.
angles is the angle range of RandomOBBRotate, (0, 0) means no rotation. Because OBBRandomFlip can flip images horizontally and vertically, we only set angles being (0, 90) in experiments.
vert_rate is the probability of the vertical rotation (rotate 0, 90, 180, 270 degrees).
vert_cls is a list containing the classes whose bounding boxes are actually horizontal. If an image has a vert_cls instance, RandomOBBRotate will only do vertical rotation.

Thank you very much!
