bridge op• Data kinds: feature → image
• Call: fullseye.apply(img, "feature_to_img", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
*The figure is the actual output on a synthetic 128×128 input. Left: input, right: output. Point clouds are drawn as a top-down scatter (brightness = z), 1-D series as a line plot, volumes as the maximum-intensity projection along z, videos as the middle frame, complex images as magnitude; return values that are not pictures are shown as the values themselves.*
Sweeping knob a (0.1 / 0.5 / 0.9, the other knob at its default):
▸ feature_to_img: knob a sweep (docs site)
Sweeping knob b (0.1 / 0.5 / 0.9, the other knob at its default):
▸ feature_to_img: knob b sweep (docs site)
Stages (the ops that come before → this op, left to right):
▸ feature_to_img: stages (docs site)
On other images (synthetic scene / photo / coins. Top row: inputs, bottom row: their outputs. Knobs at default):
▸ feature_to_img: other inputs (docs site)

スカラの feature を目盛りつきの帯にして画像へ戻す —— 2-D 台帳で
125 本の op が作るのに、画像に落とせる op が 1 本も無かった sort。
★数字そのものは描かない。 文字を焼くと絵が環境に入っている書体で
変わり、同じ入力で同じ画素という契約が壊れる。描くのは値の位置で、
目盛り(0・1/4・1/2・3/4・1)が読みの手掛かりになる。数値が要るなら
`annotate_table / annotate_leader`(paper 族)に渡すこと。
• `a → スケールの上限 hi = 10 ** (4a - 2)`(a=0 で 0.01、a=0.5 で 1.0、
a=1 で 100)。特徴量は桁がまちまちなので、見たい桁をここで選ぶ。
• `b → 目盛りの張り方。b < 0.5 は **片側** [0, hi]`(左端が 0)、
`b >= 0.5 は **両側** [-hi, +hi]`(中央が 0。相関・歪度など符号の
ある量向け)。
• 上限を超える値は端で止める(帯が振り切れた状態 = 「スケールが小さい」の
合図)。★NaN / Inf は白紙を返す(振り切れと区別する)。
• 返り値: `(128, 128)` float64、白地([0,1])。

• 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.
• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
The program below has been verified to run (same input as the figure). In Studio's help this block becomes buttons that load and run it on the spot.
