In my view, they shouldn't be used as vertical flip should make it worse and if it is a model deep and well trained enough, it might probably learn which side of which whale or dolphin has a mark. Yet, if anyone has tested this on a big enough model, could you share your findings. Besides, what kind of aumentations is everyone else using, which is showing good result(or which seems to worsen, just for learning).</p>",
