Module segmentation 

Connected components labeling using Union-Find. Connected components labeling (CCL) using Union-Find.

This module implements the second stage of the pipeline, identifying and grouping dark pixels that could potentially form fiducial markers.

It provides:

• Standard CCL: Efficient binary component labeling.
• Threshold-Model CCL: Advanced connectivity based on local adaptive thresholds.

Structs

ComponentStats

Bounding box and statistics for a connected component.

LabelResult

Result of connected component labeling.

UnionFind

A disjoint-set forest (Union-Find) with path compression and rank optimization.

Functions

compute_moment_shape

Compute shape descriptors from a component’s spatial moments.

label_components

Label connected components in a binary image.

label_components_with_stats

Label components and compute bounding box stats for each.
