tb_crossing_lamp_signal — 2D typed op

• Data kinds: signal → signal

• Call: fullseye.apply(img, "tb_crossing_lamp_signal", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

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

2 灯の赤色せん光灯の明るさ(0..1)を時刻 t(配列)で返す: 形 (n, 2)、列 0 = 左、列 1 = 右。

1 灯の周期 P = 60 / flash_per_min、点灯 duty·P。右の灯は P/2 遅れ(解釈基準「交互に点滅」)。点くのは

[t_on, t_off)。`exposure` > 0 ならカメラの露光 [t, t + exposure] の平均(点灯時間の原始関数で閉形式)。

2-D 進化レジストリへ橋渡しした drive の op `crossing_lamp_signal。実装は同じで、呼び出し規約だけ op(v, a, b) に合わせてある。この op に調整点は無く、a も b` も使われない。

References (sample data, literature)

• 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.

Runnable examples (verified samples that actually call this op)

The examples below call the underlying ledger op crossing_lamp_signal. This bridge op is the same implementation adapted to the fn(v, a, b) convention, so the behaviour carries over unchanged (only the call form differs).

• poc_driving_crossing — py -3.11 examples/poc_driving_crossing.py
