regiongrowing_n — SEGMENTATION grow op

• Data kinds: images → labels2d

• Call: import fullseye as fs; fs.ledger.regiongrowing_n(feature_images, tol=0.05, min_size=1) (to call the implementation directly, import segmentation; segmentation.regiongrowing_n(feature_images, tol=0.05, min_size=1); from the registry, opssegmentation.get("regiongrowing_n"))

Usage

Segment the whole image by multi-channel feature similarity; returns a label image (regiongrowing_n).

Detailed usage guide

• halcon_segmentation family guide

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.

Runnable examples (verified samples that actually call this op)

• halcon_segmentation_tour — py -3.11 examples/halcon_segmentation_tour.py
