coat_thickness_from_image — DRIVE polish op

• Data kinds: image2d × scalar → image2d

• Call: import fullseye as fs; fs.ledger.coat_thickness_from_image(image, coat: 'float', optical_depth: 'float' = 1.3862943611198906, bare: 'float' = 0.85) -> 'np.ndarray' (to call the implementation directly, import polish; polish.coat_thickness_from_image(image, coat: 'float', optical_depth: 'float' = 1.3862943611198906, bare: 'float' = 0.85) -> 'np.ndarray'; from the registry, opsdrive.get("coat_thickness_from_image"))

:func:coat_image の逆: t = h0 ln(bare/I)/τ を [0, h0] に切る。Raises ValueError: 画像の検査、数の検査。

• 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.
