Deprecation warning in SDS_preprocess.py due to remove_small_objects(min_size=...)

[2320sharon]

Description

Running CoastSeg triggers repeated FutureWarning messages from coastsat/SDS_preprocess.py related to a deprecated parameter in skimage.morphology.remove_small_objects.

The warning points to:

File: coastsat/SDS_preprocess.py

Line: 973

Warning

C:\development\doodleverse\coastseg\CoastSeg\.pixi\envs\default\Lib\site-packages\coastsat\SDS_preprocess.py:973: FutureWarning: Parameter `min_size` is deprecated since version 0.26.0 and will be removed in 2.0.0 (or later). To avoid this warning, please use the parameter `max_size` instead. For more details, see the documentation of `remove_small_objects`. Note that the new threshold removes objects smaller than **or equal to** its value, while the previous parameter only removed smaller ones.
  cloud_mask = morphology.remove_small_objects(

This warning is emitted multiple times during execution.

Cause

skimage.morphology.remove_small_objects() has deprecated the min_size parameter as of scikit-image 0.26.0. The code in SDS_preprocess.py still appears to use min_size, which will eventually break once support is removed in scikit-image 2.0.0 or later.

Suggested fix

Update the call at SDS_preprocess.py:973 to use max_size instead of min_size, while preserving current behavior as closely as possible.

One thing to note from the warning:

max_size removes objects smaller than or equal to the threshold

min_size previously removed objects only smaller than the threshold

So the replacement may need an off-by-one adjustment depending on intended behavior.
