Add DeleteChannelD inverse equivalent of RepeatChannelD #1567

Closed wyli closed 3 years ago

wyli commented 3 years ago

In the liver and tumor segmentation model, it's possible to approximate the Brain Segmentation workflow with RepeatChannelD to enable usage of ConvertToMultiChannelBasedOnBratsClassesd. However this results in greater, unnecessary memory usage.

Adding a DeleteChannelD transform would allow the duplicated channels to be pared down before feeding into the network.

Hi @wyli ,

Thanks for raising this, I think Tam is working on the PR to address it: https://github.com/Project-MONAI/MONAI/pull/1569.
