Pull request overview

Adds lightweight image-preprocessing exports and extends the segmentation data object with visualization-related defaults, aligning the data model with expected UI/visualization settings.

Changes:

• Adds src/image_preprocessing/functions.py to re-export selected preprocessing functions (enhance_clahe, enhance_gamma).
• Extends CeusSeg with default visualization parameters (CLAHE clip limit, gamma, per-view width scales, Philips CEUS toggle).
• Includes empty __init__.py modules to ensure packages are importable.

src/image_preprocessing/options.get_im_preproc_funcs() already discovers preprocessing functions dynamically from image_preprocessors/, but this new functions.py file hard-codes and re-exports only enhance_clahe and enhance_gamma. This creates two competing “sources of truth” for available preprocessors and is likely to drift as more plugins are added.

Consider either removing this module and relying on the existing plugin discovery, or updating it to expose all preprocessors in a single, consistent way (e.g., via get_im_preproc_funcs() or an explicit, complete __all__).

Suggested change

	from .image_preprocessors.enhance_clahe import enhance_clahe
	from .image_preprocessors.enhance_gamma import enhance_gamma
	from .options import get_im_preproc_funcs
	# Discover all available image preprocessing functions using the existing
	# plugin mechanism and expose them as module-level attributes. This keeps
	# a single source of truth for available preprocessors.
	_PREPROCESSOR_FUNCS = get_im_preproc_funcs()
	# Make each discovered preprocessor directly importable from this module,
	# e.g. `from .functions import enhance_clahe`.
	globals().update(_PREPROCESSOR_FUNCS)
	# Export all discovered preprocessors.
	__all__ = sorted(_PREPROCESSOR_FUNCS.keys())
