A question about spatial_transforms #45

Closed EricKani closed 4 years ago

EricKani commented 5 years ago

Hi,

Thanks for your sharing of your augmentation code. I have a question about ''augment_channel_translation'' in ''spatial_transforms.py''.

What is the meaning of this augment method? Does it in order to prevent the impact of poor registration between different modality of one object？（different modality: like RGB and Depth in netural image; CT and MRI and PET in medical image. One modality is one channel)

Thanks.

Best,

Eric Kani

Hi Eric, exactly. It will misalign the 'color' channels (translation only) to simulate bad registration. I have not used it though, so I cannot say how well this works as an augmentation. Best, Fabian
