one argument seems a little bit misleading in 'main.py'

[shiqi1994]

parser.add_argument('--patch_size', type=int, default=40, help='Size of cropped HR image')
I read the code of functions related to this argument, Is 'patch_size' the size of the net input? For example, for DBPNx4 model, if 'patch_size' is the input size '40x40', the hr_train_dataset should be a set of images sized 160x160 . Is it right?
