tb_random_scale — 2D `typed` op

• Data kinds: points → points

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

Usage

Applies a uniform scale `s ~ U(lo, hi) about the origin and returns (scaled, s)`.

> The detailed description below is the original text — the summary and the headings are translated.

`scaled = points * s。bbox 対角長はちょうど s 倍になる(s > 0` なので

`max/min が共に s 倍 → 対角 ‖max-min‖ も s` 倍)。物体スケールの

ばらつき(距離/センサ倍率)を学習に注入する。`0 < lo <= hi` を要求(fail-closed)。

2-D 進化レジストリへ橋渡しした 3d の op `random_scale。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。

• 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)

Ops the type connects to (they accept `points` as input)
