wipe_coverage — DRIVE polish op

• Data kinds: image2d × scalar → table

• Call: import fullseye as fs; fs.ledger.wipe_coverage(image, res: 'float', threshold='otsu', coat=None, optical_depth: 'float' = 1.3862943611198906, bare: 'float' = 0.85, min_area: 'int' = 4) -> 'dict' (to call the implementation directly, import polish; polish.wipe_coverage(image, res: 'float', threshold='otsu', coat=None, optical_depth: 'float' = 1.3862943611198906, bare: 'float' = 0.85, min_area: 'int' = 4) -> 'dict'; from the registry, opsdrive.get("wipe_coverage"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

拭けた所(明るい = 膜が消えた所)の面積を画像から読む。2 値化と連結成分は detect.segment_objects(Otsu が既定)。

返り `area(拭けた画素 × res² [m²])、fraction、largest_area、n_regions、mask、threshold`(Otsu の

しきい値 = 拭けた側の最小と残った側の最大の中点で推定)、`coat を渡せば residual_at_threshold`(しきい値の明るさが意味する

残った膜の厚さ —— 読んだ帯は「除去 ≥ h0 − この厚さ」の所)。Raises ValueError: 画像の検査、res ≤ 0、拭けた所も残った所も

無い(しきい値が決まらない)。
