Multi-class registration for 2D registration

[ku294714]

Hello all,

I would like to use 2 class labels for 2D registration task.

Do I need to add a channel in the label tensor to make it as (batchsize * 2 * dim1 * dim2) shape?

Also, what is the difference between globalnet (used in 2D registration) and localnet (used in 3D registration)?

Hi @wyli ,

Could you please help share some comments here? I think you are expert on registration tutorials.

Thanks in advance.

Hi @wyli , I am not very sure about the GlobalNet and LocalNet, could you please help share some comments here?

Thanks in advance.

Thank you for the reply @wyli . Can you ask tell me about multi class registration? For 2D registration, I want to use 2 labels. Do I need to add a channel in the label tensor to make it as (batchsize * 2 * dim1 * dim2) shape?

Yes I guess the label tensor should be in that shape so that it could be warped
