What do the float numbers in unpreprocess function mean? (in train.py)

[Yuchen-Song]

Where do these float numbers come from? I could not find any reference to them.

MVSNet_pl/train.py

Lines 32 to 41 in b18b5ee

	class MVSSystem(pl.LightningModule):
	def __init__(self, hparams):
	super(MVSSystem, self).__init__()
	self.hparams = hparams
	# to unnormalize image for visualization
	self.unpreprocess = T.Normalize(mean=[-0.485/0.229, -0.456/0.224, -0.406/0.225],
	std=[1/0.229, 1/0.224, 1/0.225])
	self.loss = loss_dict[hparams.loss_type](ohem=True, topk=0.6)
