class_2dim_sup — SEGMENTATION classify op

• Data kinds: image2d × image2d × mask → mask

• Call: import fullseye as fs; fs.ledger.class_2dim_sup(image1, image2, ref_region) (to call the implementation directly, import segmentation; segmentation.class_2dim_sup(image1, image2, ref_region); from the registry, opssegmentation.get("class_2dim_sup"))

Usage

Supervised classification in a 2-channel feature space: pixels inside the distribution of ref_region (class_2dim_sup).

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
