Horizontal flip augmentation changes angle

[meghbhalerao]

Hi all, this might be a basic question, but in this line, and other lines in the dataloader, the RandomHorizontalFlip() is one of the augmentations, but would that not change the rotation angle of the image, hence consequently changing the ground truth. Is this being handled anywhere (i.e. changing the ground truth label when RandomHorizontalFlip() augmentation happens )?
Thank you!

Random horizontal flip does not change the rotation angle. For example, if an object is up-standing in the image, then it would still be up-standing after the horizontal flip.

Oh yes, absolutely. You are right. That did not come to my mind. Thank you.
