WebJan 16, 2024 · ghost commented. RandomRotation takes a range of degrees to randomly sample the angle from. By requesting (rot, rot) there will be no randomness, since the only value that can be sampled is rot. If you want to sample from (-rot, rot), either pass that or use the shortcut RandomRotation (rot). Filling all channels with 0 is the default behavior. WebDec 5, 2024 · Image Rotation. Image rotation is one of the most commonly used augmentation techniques. It can help our model become robust to the changes in the orientation of objects.
