tacslip op• Data kinds: image2d × scalar × scalar → table
• Call: import fullseye as fs; fs.ledger.marker_detect(m, dark: 'float', r_px: 'float', binary: 'bool' = False) -> 'dict' (to call the implementation directly, import tacslip; tacslip.marker_detect(m, dark: 'float', r_px: 'float', binary: 'bool' = False) -> 'dict'; from the registry, opsdrive.get("marker_detect"))

マーカー像 m(:func:marker_image)→ マーカー中心。`weighted`(主、(N, 2) の (x, y) [px]): 高しきい値 0.5·dark の連結成分
(:func:blob2d.blob_label)を本体とし、低しきい値 0.08·dark の画素(縞)を距離変換で最近傍の本体へ割り当て、m を重みにした重心を
反復ガウス重み(σ = r_px)で精密化。`weighted_plain = 精密化前。binary=True なら binary = :func:blob2d.blob_features` の
row/col(二値重心、周長・凸包まで計算するので 1,000 個で 0.4 s)。縁に触る成分は捨てる。`n` = 本体の数。
縞を本体から切るのは、滑り環で隣接間隔が 8 → 6 px に縮むと低しきい値の縞が繋がって 1 成分に併合するから(実測)。
Raises ValueError: m が 2 次元でない、dark が (0, 1] の外、r_px ≤ 0。
