hx_gen_disc_se — 2D `halcon_ext` op

• Data kinds: image → region

• Call: fullseye.apply(img, "hx_gen_disc_se", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

• HALCON equivalent: gen_disc_se (the HALCON reference is a useful guide to its meaning and parameters)

Usage

Generate a disc structuring element as a region (radius a).

• 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.
