pegsim op• Data kinds: image2d × image2d × image2d → matrix
• Call: import fullseye as fs; fs.ledger.coverage_edge_points(gray, inside, outside, min_contrast: 'float' = 25.0, exclude=None) -> 'np.ndarray' (to call the implementation directly, import pegsim; pegsim.coverage_edge_points(gray, inside, outside, min_contrast: 'float' = 25.0, exclude=None) -> 'np.ndarray'; from the registry, opsdrive.get("coverage_edge_points"))
Returns subpixel edge points (u, v) from the brightness (coverage) of an anti-aliased boundary: for a pair where pixel p is on the inside side and the pixel 2 steps ahead is outside, edge position = (−0.5 + f_p + f_q) pixels from p (f = inside coverage of that pixel = (I − I_out) / (I_in − I_out)).

4 軸方向(上下左右)の対を全部使う。inside / outside は bool マスク(同じ形)、gray は明るさ(float)。min_contrast 未満の対は捨て、exclude のマスクに掛かる対も捨てる。返りは (N, 2) の (u, v)(列・行)。Raises ValueError: 形が違う、対が 1 つも無い。
