KeepLargestConnectedComponent: Is input image or label?

def __call__(self, img: NdarrayOrTensor) -> NdarrayOrTensor:

With the given matrix format examples, I understood input as label, rather than image.

Is there any reason behind this? I think with "label", the meaning is clearer for users if I did not misunderstand.

Hi @Joeycho, the img here is just the generalized input image, also to keep it consistent with other transforms. The docstring also explains what data should be entered in detail. Thanks for your advice!

I see. I just checked other transforms, such as LabelFilter, Fillhole, etc. Indeed. I think people can understand what the given transform does with docstring in class.
