Transform Landmark Support

[lukas-folle-snkeos]

It would be great if the monai.transforms.spatial transformations would also be able to operate on 2D or 3D points.

For example:
The Resize transformation could do the following:
image [100, 100] -> image [10, 10]
landmark (20, 40) -> landmark (2, 4)

Is something like this planed?

thanks for the suggestion, some coordinate operations are implemented as part of the bounding box transforms (in monai.apps) for detection tasks

MONAI/monai/apps/detection/transforms/array.py

Lines 267 to 270 in e5cf74a

	class ResizeBox(Transform):
	"""
	Resize the input boxes when the corresponding image is
	resized to given spatial size (with scaling, not cropping/padding).

enhancing/integrating these into the core transform modules doesn't currently have a high priority...if we can identify some critical use cases, we'll have more developments in these modules.

Thanks for the hint!
