koschmieder — DRIVE env op

• Data kinds: any × any × scalar × any → any

• Call: import fullseye as fs; fs.ledger.koschmieder(L0, L_h, beta: 'float', d) (to call the implementation directly, import driveenv; driveenv.koschmieder(L0, L_h, beta: 'float', d); from the registry, opsdrive.get("koschmieder"))

Usage

Koschmieder's law: apparent luminance of an object at distance d, L = L₀ e^{−βd} + L_h (1 − e^{−βd}) (arrays allowed).

• 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.
