Hi,

that means all 0 in the label became

I am working on a project and I need to crop the ct images in the same way as the label, that means all 0' in the label became 0 in the CT as well;
I'm using RandCropByLabelClassesd

    RandCropByLabelClassesd(keys=["image"], label_key="label", spatial_size=None, ratios=None, 
                            num_classes=3, num_samples=1, ),

there is a way to do this with monai.transform?

I guess you can include label in the keys:

RandCropByLabelClassesd(keys=["image", "label"], label_key="label", spatial_size=None, ratios=None, 
                            num_classes=3, num_samples=1, ),

I did it, but the ct still the same.

Hi @oscarramirezs, since it is a random crop, if you didn't specify the spatial_size, it will keep the original size of the label. Thanks.
