I wonder why we need do it?Flip image is some kind like data argument? if self.set_name=='train' and np.random.random(1)>0.5: image1 = image1.transpose(PIL.Image.FLIP_TOP_BOTTOM) image2 = image2.transpose(PIL.Image.FLIP_TOP_BOTTOM) if self.set_name=='train' and np.random.random(1)>0.5: image1 = image1.transpose(PIL.Image.FLIP_LEFT_RIGHT) image2 = image2.transpose(PIL.Image.FLIP_LEFT_RIGHT)

Yes. It is for augmenting training data. As mgPFF is a low-level vision method, meaning that it does not need to understand high-level semantics, such flip and flop augmentation can be applied here. But it is optional when you have enough training data.
